[Rivet] rivet and problems with python lib

[Zenonas Zenonos]

Hello Andy

thanks for looking at this.
Previously, I was running with python 2.5.4p2, Rivet
1.2.1, slc4_amd64_gcc34, AGILe-1.1.4 and it was working fine.
Now, I moved to py 2.6.2,  rivet 1.4.0, x86_64-slc5-gcc43-opt, AGILe-1.2.1
and I'm having this python problem.

The result of doing "locate libpython2.6.so.1.0" interactively is good
/usr/lib64/libpython2.6.so.1.0
but empty when running with bsub. Which path must be normally taken when
running?
In the other hand, I saw that  libpython2.4.so.1.0 exist when running with
bsub. What might be the solution to that?
How can I point to libpython2.6.so.1.0 correctly when running with bsub?

Thank you!
