As you already said, the problem is that all tasks need an AFS token.
In our cite we have also PVM running under an AFS file system. 
Before compiling the pvm system I only changed one entry in the conf/$ARCH.def
file:

You should extend the ARCHCFLAGS by

-DRSHCOMMAND=\"/usr/afs/bin/rsh\"

where /usr/afs/bin/rsh is the AFS specific rsh in your system (there should
be one!). This AFS-rsh command then handles the AFS token.

Good luck!
