Dear Scott,
yes it works with the n32 libs. It is sufficient to place the resulting libiv_ogl.so in the directory where
the n32-perfly gets started (as libiv.so) so you do not need to copy it into /usr/lib32/libpfdb/ . The same
procedure fails for the 64-lib. I don't know why, but I get a core dump... But I will keep trying to get the
64-perfly working.
