If you look at the line just above the CFLAGS one in configure.ac
there's a horrible little find/sed script that I had to come up with
to work out the path to the lib directory because homebrew sticks them
in a directory named 10 or 11 or whatever depending on the version of
gcc. Perhaps it can be generalised for Macports too?
