Well, pkg-config is not part of Mac OS X (as of 10.4.8).

$ pkg-config --libs xrender
-bash: pkg-config: command not found

These seem to be the only .pc files on a Mac OS X system. No xrender.pc.

$ locate .pc | grep '\.pc$'
/usr/lib/pkgconfig/gimpprint.pc
/usr/lib/pkgconfig/libexslt.pc
/usr/lib/pkgconfig/libxml-2.0.pc
/usr/lib/pkgconfig/libxslt.pc
/usr/lib/pkgconfig/openssl.pc
