[Rivet] rivet and problems with python lib

[Andy Buckley]

Hi Zenonas,

This does indeed look like an environment issue: does your batch system 
have the same operating system (and Python version) as the workstation 
on which you've successfully run it interactively? Are the same 
environment scripts being sourced?

Might be worth submitting a "locate libpython2.6.so.1.0" job to your 
batch system via bsub, to see whether that library is available at all.

By the way, I guess from the bsub output that you've been running this 
on lxplus/lxbatch -- why not use the pre-installed Rivet and AGILe in 
the Genser repository?

Cheers,
Andy
