I think I have partially figured out what is going wrong. The 
(successful) installation of AGILe/rivet using my
local installation of HepMC runs into segmentation faults, because the 
generator libraries loaded by AGILe
are all 32 bit ones, e.g.:

    AGILe.Loader: TRACE  Found 
/afs/cern.ch/sw/lcg/external/MCGenerators/pythia6/416/slc4_ia32_gcc34/lib/libpythia6_dummy.so

Is it possible to give AGILe a certain lcg-tag to 'dot slash configure' 
with? I think there was something like that in a former bootstrap
script.

I still don't know why the cern's HepMC version doesn't work for me :(

In order to use LHAPDF as it is installed at /afs/cern.ch... one only 
needs to add the appropriate path to LD_LIBRARY_PATH, right?

Cheers,
