That's good.  The scheme I proposed supports that approach.

Excerpt from http://modules.sourceforge.net/
===========
% module load gcc/3.1.1 
% which gcc 
/usr/local/gcc/3.1.1/linux/bin/gcc 
=======  That's /prefix/ = /usr/local/gcc/3.1.1/linux/
Now we'll switch to a different version of the module 
% module switch gcc gcc/3.2.0 
% which gcc 
/usr/local/gcc/3.2.0/linux/bin/gcc 
=======  That's /prefix/ = /usr/local/gcc/3.2.0/linux/

So in this case, you could:
=======
% module load gnucap/1.0
% which gnucap
/usr/share/gnucap/1.0/x86_64-linux-gnu/bin/gnucap

% module switch gnucap gnucap/2007-05-06
% which gnucap
/usr/share/gnucap/2007-05-06/x86_64-linux-gnu/bin/gnucap
=======

So it looks like it should work as I proposed.
