Most of the sample programs will automatically invoke 'smake' (a parallel make
program) when you type just 'make'. On my IRIX 6.5.17 system these translate to:
l 0 0 dev.sw.make usr/sbin/smake
l 0 0 eoe.sw.base usr/bin/make
The versions of dev.sw.make I have installed is:
% versions -n dev.sw.make
I = Installed, R = Removed
Name Version Description
I dev 1278316532 Development System, 7.3.1.2
I dev.sw 1278316532 Development Software, 7.3.1.2
I dev.sw.make 1278316532 Parallel Make Utilities

That's very unusual, never seen that happen. I'm wondering if you don't have
'smake' so something else is being used in its place

The documentation on the Makefiles is admittedly pretty light. Most of them
have a little section at the top describing the targets (dso, opt, etc). The
rest, for when you feel ambitious, is almost all contained in
/usr/share/Performer/src/pfmakedefs and pfmakerules, which are included by the
other Makefiles.

Finally something I know the answer to. :-)
As of a very recent IRIX 6.5.x (perhaps x=15) we've started to bundle the
'ldd' command, so: 'ldd /usr/sbin/perfly'
On systems prior to the release containing ldd, you can get similar
information from: elfdump -Dl /usr/sbin/perfly
