Ah; my mistake. I had assumed that they were providing source.

For a single user, 6.3 is probably preferable to 6.2. The occasional
user-visible change is probably outweighed by additional
The main reason to stick with 6.2 is if you are investing significant
time and effort in creating scripts (or course material), where any
incompatible change would be a major inconvenience.

When compiling from source, one thing to bear in mind is that you also
need the development packages (with the headers and .so symlinks) for

Installing dependencies is highly platform-specific. Once you have all
of the dependencies, "configure ; make ; make install" will often
suffice if you don't need some of the less common features.
