at many of the larger sites i've worked with, they use environment modules
to solve this.  modules is a bit hacky but ultimately it does work pretty

basically, software is installed in pkg/version specific directories
like /sw/<pkg>/<vers>/, and then a module file is created to do all the
required environment settings (PATH, LD_LIBRARY_PATH if necessary, etc).
users can then load/unload individual packages, and there's a very crude
system of dependencies in case you have interdependencies between modules.
users can also query what tools/versions are available, and you can feel
much less stressed that installing a new version will break things for
the entire site :)
