John: I would refrain from installing the old default package 
"environment-modules" from the Linux distribution, since it doesn't seem 
to be maintained any more.

Lmod, on the other hand, is actively maintained and solves some problems 
with the old "environment-modules" software.

There's an excellent review paper on different module tools: "Modern 
Scientific Software Management Using EasyBuild and Lmod",
