Missing nothing, but certainly experiencing the delights of SL5. What 
you're doing is right, but the version of SWIG on SL5 is sufficiently 
old that it can't parse the HepMC header file. I think the easiest way 
around is to make your own hepmc.py and hepmc_wrap.cc against HepMC 2.03 
(I'm assuming it's not HepMC 2.4, since that should work out of the box) 
on a more up-to-date OS and then copy them into place. After the work 
that Frank did last week, the head version should now do all the HepMC 
compatible stuff in the C++ rather than the Python interface.
