Actually, it was /opt/local/bin/fc-match (macPorts?). I have _three_ of them:
peter-dalgaards-iMac:~ pd$ ls -l /usr/X11/bin/fc-match
-rwxr-xr-x 1 root wheel 64416 Feb 11 2010 /usr/X11/bin/fc-match
peter-dalgaards-iMac:~ pd$ ls -l /usr/local/bin/fc-match
-rwxr-xr-x@ 1 root wheel 1476560 Oct 21 2008 /usr/local/bin/fc-match
peter-dalgaards-iMac:~ pd$ ls -l /opt/local/bin/fc-match
-rwxr-xr-x 2 root admin 14792 Mar 16 16:52 /opt/local/bin/fc-match
Doesn't look like they are behaving any different, though.

You're assuming (in fact, correctly) that I was using Simon's build, but my locally built version is similar. That doesn't appear to use pango either; I have a Portfile for pango-devel, but it must have failed to build.
