[Rivet] Rivet on Genser

[Andy Buckley]

It looks to me like you don't have the appropriate compiler set up: the 
complaint about the "GLIBCXX_3.4.9" version not found is indeicative of 
this mismatch. It happens a lot because none of the LCG applications use 
the default SLC5 compilers etc.

Benedikt/Genser, could a central "LCG environment" script (or set of 
scripts) be provided so that the correct environment for Genser's 
building and users' running of generator codes is well-defined? I've 
looked for such a thing before, but as far as I'm aware it doesn't exist 
in or under /afs/cern.ch/sw/lcg.

Such env scripts would at least need to specify the GCC and Python 
versions... those are already required to be set to particular versions 
to run the generator packages, since they were *compiled with specific 
versions, but what those versions are isn't at all obvious!

IMO it would also make sense for all the Genser packages' setup scripts 
to source the appropriate main compiler/Python environment. If it helps, 
I have a Python script which returns the appropriate LCG tag for a given 
machine, with architecture overrides possible... I offered this to LCG 
before, but despite interest it never seemed to go anywhere. I use it 
with success in my own lxplus setup scripts.

Thanks,
Andy
