[Users] Help w/ MPI link errors

[Steven R Brandt]

I think it turned out to be my error. I used gcc 4.0, but f77 (based on 
something older than 4.0). I told it not to use an f90 compiler. The 
mixed versions caused Cactus to get the link line mixed up (I could fix 
it by hand). The nature of the error messages, however, had me confused 
for a bit.

Cheers,
Steve
