It appears as if this diff was merged for 0.75 portable.

Preliminarily, it appears as if it broke the MacPorts checks for bison.

FWIW, /usr/local is a default path in MacOS, /opt/local is what MacPorts uses.

I'm attempting to undo the damage at the moment. I had previously
replied to Lucas off list. No one has responded via IRC yet.

Thanks
