I brew installed potrace v 1.12 When I try to gem install potracer, I get: ERROR: Error installing potracer: ERROR: Failed to build gem native extension.

Hi there. It should work fine with potrace 1.12, that's what I'm running on my box. It appears that it's not able to locate where homebrew installed libpotrace. It checks /opt/local/lib, /user/local/lib, /usr/lib. It will also check the libdir/includedir given on the command line.
