ok. thx. Yes I'm reading the documentation of "modules" and I find some
examples.

So I must have a directory (for example /opt/compiler/gcc) with the
different versions of gcc (4.1 and 4.4 in my case). Then the module tcl
script chooses one and exclude the other, does it ?

in order to have these gcc directories can I just copy the files from
the installed rpm ? or must I compile the different gcc versions by myself ?

Thx a lot!
