I'm not sure why it's saying that the freetype backend could not be
enabled. Perhaps it's not finding the freetype library? (The error
message there certainly isn't very informative.)

But the lack of FcFini should not be a problem at all. If that is
causing the freetype backend to be disabled, (and I really doubt that
it is), then that would be a bug in cairo's configure script.

You'll probably need to look at config.log to see what's actually not
working here.

It's strange that in the first case the messages are getting
scrambled. Again, it's likely not FcFini causing any problem. It's
more likely to be the "checking for FREETYPE" part, (though whatever's
causing FcFini to not be found might also be causing freetype to not
be found).

But I don't know anything about the OS X linker, and in particular, I
know nothing about what doing a "universal build" might change. So
you'll need to find somewhere/someone to help debug the
system-specific issues here.

None that I can think of. Does anything change if you export these
variables?

Again, I don't think FcFini has anything to do with your problems.
