Rolling back to lirc-0.8.1 solved this problem, but I've encountered
another.  As far as I can remember, and as far as I can tell from the
docs, native lirc support just required adding the enable lirc flag to
configure, but I seem to be having a problem.

configure is reporting lirc support enabled, but lirc isn't actually
being linked in.  The lirc client libraries are in /usr/local/lib,
which is in my /etc/ld.so.conf

Options:  --enable-opengl-vsync --enable-xvmc-opengl

I've done a make distclean and no dice.  Any clues, anyone?
