Well, since these aren't in RPMs and dont follow the one-true-way ... 
we are destined to roam the backwaters of true clusterdom.  Only two 
Gaussian versions?  I presume g03 of various flavors?  Or g98 + g03 ...

Iv'e been worrying about whether I should try a versioning bit in my 
NCBI rpms.  So that they install into /path/version_number, and then 
soft link the bins and man pages into the right locations.  I don't have 
a good solution I am happy with here.
