Hi again,

this problem is very likely to be related to LHAPDF of version 5.5.0
For some reason AGILe is unable to load libLHAPDF.so if the Sherpa job
is issued to the batch farm whilst LHAPDF of version 5.5.0 is installed.
However, running the same job interactively works just fine with
libLHAPDF.so being successfullty loaded by AGILe.

This behaviour appears to be independent of Sherpa being configured
with --enable-lhapdf or not.

So uninstalled LHAPDF 5.5.0 and installed LHAPDF 5.3.1 instead and now
this problem is gone.
