I'm trying now to build it from source, and it's got a set of dependencies that aren't included by default on Mac OS X. So I'm doing a bit of downloading with Fink to satisfy the missing pieces. We'll see how it goes.
The first broken dependency was "ltdl.h" from libtool. It's actually on my system, just not where the configure script expects it. So I ran this command:
sudo ln -s /usr/share/libtool/libltdl/ltdl.h /usr/include/ltdl.h
Next it couldn't find the "glib-config" script, so I installed glib 1.2.10-8 from Fink.
Finally it complained about "gettext" with the message "error: Cannot find gettext -- do you need to build -lintl?"
After attempting to solve this issue unsuccessfully I gave up. Next!
