Didn't dmacks say a week ago on this list he'd look into this?

The setpgrp function changed its definition between Tiger (int
setpgrp(pid_t pid, pid_t pgrp);) and Leopard (pid_t setpgrp(void);)

The ptlib sources are actually aware of this, they have (in 
include/ptlib/unix/ptlib/pmachdep.h) the following piece of code:

Apparently, they are wrong.
