Chris,

I've had similar problems on our SUNMP machine. If you do not need 
MP facilities, the easiest way is to run SUN4SOL2 binaries on
your SUNMP machines.

At our site, we have several Solaris 2.5 machines, so all I needed
to do was to link all SUNMP directories of the PVM tree to SUN4SOL2
(ln -s SUN4SOL2 SUNMP), and it worked.

I am not sure how to compile SUN4SOL2 binaries on a SUNMP machine -
PVM automatically determines the host architecture when building.
Maybe setting PVM_ARCH to SUN4SOL2 could help.
