Hi Silvia,
Sorry it took so long to get back to you. It seems the problems you are
seeing come from the cernlibs. I have tested some very basic simulation
using gsim_bat but I would like you to verify that this works for you. I
put it into /group/clas/builds/test3 and you should source this environment
script before running anything:

ssh ifarm1102        #  <-- this is the only rhel6 interactive node

source /group/clas/builds/test3/environment.csh

After this is done, you should see that gsim_bat is in your path and it
should be located here:
which gsim_bat
/group/clas/builds/test3/bin/gsim_bat

Once you test it, I will move the environment script to what I hope to be
the "canonical" location of the CLAS run-time environment:
/group/clas/builds/environment.csh       # <-- for tcsh and csh
/group/clas/builds/environment.sh         # <-- for bash and sh

But know that this will ONLY work on rhel6 systems and there is only one
interactive node: (ifarm1102). This should fail on ifarm1101 which is the
older rhel5 system.
