Compiling the module with "-pg" and linking in the profiling lib are no problem... But that doesn't seem to do it. gprof wants to work on "a.out", which I guess would be /usr/bin/perl in this case. I'd be willing to recompile Perl if that would do it, but I'd like to hear that someone has done it successfully before first. My programmer's intuition is telling me it won't work...
