Well, it looks like it is the assignments in the file “QCD/OPEm.m” that
are causing the error message. Below follow the suspects

If you can fix the problem, your’e welcome to commit the fix back.
I suppose one could use “Greater /:” instead of “Re/:”, but I’m not sure
it’s a good idea mess with a so commonly used function.

I guess I could use a copy of mma 5.0…

Cheers, Frederik
