Set the shell variable:

setenv CCOPTIONS '-pcc'

And then rebuild perl on you convex (make clean and then make).

If you just set the '-pcc' flag you will only effect the compilation
of the perl binaries not its loading.  The Configure command is carefully 
to  separate out the compilation flags from the load flags.  Unfortunately
it does not prompt you for any load flags?

The problem that you are seeing under Convex OS 8.x is due to the use
of a busted setruid/seteuid POSIX compliant library.
Since you did not specify '-pcc' on the load you get the POSIX library.

Under Convex OS 9.x the get group system call will fail if you don't
specify the "-pcc" option on the load.  Again, since you did not specify
the "-pcc" on the load command you get POSIX compliant library.
Under Convex OS 9.x they fixed setruid/seteuid but the changed
the definition of the array that getgroups returns form a
int * (32 bits) to a short * (16 bits).
