Ok, that almost worked.

I had to add /Library/Frameworks/Mono.framework/Versions/Current/bin to my path
or it would complain that "mprof-report" could not be found.

This did in fact get the profiler to work properly, but when running mono with
the --profile switch fsc.exe does now crash. (It runs fine if the switch is not
used.)
