Building LPSolver binary from source - for MAC OSX. How to build and install the lp_solve Java extension on Mac OS X. In one of my recent work on building Analytics by processing very huge volume of data, has some tight time limits on how quickly it needs to be completed.

All software are programs, which are also called source packages. So all source packages need to be built first, to run on your system. The binary packages are one that are already build from source by someone with general features and parameters provided in the software so that a large number of users can install and use it. Binary packages are easy to install. But may not have all options from the upstream package. So for installing from source, you need to build the source code yourself. That means you need to take care of the dependencies yourself.
Also you need to be aware of all the features of the package so that you can build it accordingly. Advantages of installing from source:. You can install the latest version and can always stay updated, whether it be a security patch or a new feature. Allows you to trim down the features while installing so as to suit your needs.
Similarly you can add some features which may not be provided in the binary. Install it in a location you wish. In case of some software you may provide your hardware specific info for a suitable installation. In short installing from source gives you heavy customization option at the same time it takes a lot of effort, while installation from binary is easier but you may not be able to customize as you wish.
Update: Adding the argument related to security in the comments below. Yes it is true that while installing from binary you don't have the integrity of the source code. But then it depends as to where you have got the binary from. There are lots of trusted sources from where you can get the binary of any new project, the only negative is the time. It may take some time for the binary of the updates or even a new project to appear in our trusted repositories.
And above all things, about software security, I'd like to highlight this hilarious provided by in the below comments. A source file contains the original code as written by the developer in whatever language he/she chooses (C, C, Python etc),and is generic. It isn't specific to any distro and in many cases to any operating system. A package (RPM or DEB for example) is the binary executable (or interpreted script etc) pre-prepared for your particular distro. The task of preparing the source for compiling (adding any necessary patches etc), the actual compile, creating distro specific config files, creating pre and post install scripts etc are all done for you by the package maintainer. In other words, all the donkey work has been done for you in a package, whereas you'll need to do it yourself if you choose to install from source. Apart from the other answers, I would like to add something: If you decide to compile a program by yourself, you need to think that compiling is not something you do only once.
You will probably need to subscribe to the development mailing list of the applications you decided to compile and stay up to date with the new versions and, especially, the security updates. Every time the application is updated you will have to recompile the new version so, just keep in mind that you will have to spare some of your time every week. If you cannot afford that, it is better to let the package maintainer do that job for you.
Building from the source allows to specify architecture of exactly your machine. New CPUs have additional instructions that compilers do understand, squeezing out a little bit of performance. Pre-build packages usually count on the most archaic CPU still in common use.
This is mostly important for project-critical applications that use CPU very heavily, such as tools of bioinformatical pipeline, for instance, or geophysical modelling tools. Such software runs in a very controlled environment, does not feature access control on its own, so seldom has security bugs so urgent that they must be patched in days or hours. Almost never it needs to run on a different machine with initially unknown architecture. Yes, I known, computers are very very very fast now and any efforts or actions you take are very very very expensive, but on the third day of sitting and waiting your program to complete (this is the situation I am talking about) such truths start looking questionable.

Differently, applications like browsers and the like should be better used from the maintainer repository (and not from some downloaded pre-built packages), as it is very important to keep them up to date. One way to get the best of both worlds (up to date software, simple install/uninstall, incorporate most distribution tweaks and adaptations, can optimize for local requirements), while the costs (have to keep up to date yourself, watch out for bugs and last-minute patches, follow development, you are on your own with respect to bug fixes and incompatibilities between versions) can't be mitigated (much), is to build your own packages, starting with the source packages from your distribution.
Yes, it is more work than just building and installing.
