[Rivet] Problem with AGILe and FHerwig

[David Grellscheid]

Hi Adam, Hi James,

I have also seen some problems when mixing HPC's gfortran with Apple's 
gcc versions. Once I had a consistent setup of gcc, g++ and gfortran, 
the problems went away. You could try installing all of gcc from HPC, 
and make sure that /usr/local/bin is first in your PATH. To check that,
'gcc -v', 'g++ -v' and 'gfortran -v' should all be the same version.
