... and on binary systems you can always use my usual trick:
$ mkdir ~/usr
$ ./configure --prefix=$HOME/usr
$ make install
Most software would work. Actually I haven't yet seen software which wouldn't.
Idea is simple: do NOT install packages onto whole system, keep them local to user(s). Doing all that from under user account has added bonus that no left stuff will be install where you do not want it.
If you need to customize packages often, then use Gentoo.
