Says something like '{blah} not in executable format' when I try and execute gprof as follows: gprof pkg_info.gmon I think I chased this problem down to an inconsistency with GNU binutils before, but please note that I haven't had an opportunity to update my system for ~2 months (don't have direct access to the Internet; have to traffic files back and forth via my iBook and I've been busy lately with other things..). So I'm running 8-CURRENT, updated as of sometime 3rd week of October.. Also, depending on what you're trying to compile for profiling purposes, you will have to recompile all dependent libraries, not just libc. I had to recompile libfetch and libarchive for pkg_install, otherwise stuff segfaulted and coredumped every time I ran the profiled apps. Thanks, -Garrett
