gobject-introspection is available nowadays, only that it is disabled if
you do a universal build.
The universal build is a bit tricky to handle due to the design of gobject
introspection. Anyway the universal builds are no longer maintained, the
last version of Mac with a 32 bits kernel is Lion and the last Mac with a
32 bits arch is from 2006.

with a couple of friends, and it works just fine. The bad news is that I
started this 2 years ago based on the gstreamer.com fork, and my attempts
to feed back these fixes into the mainstream went nowhere. This may well be
because I wasn’t aware of the differences between the gstreamer.com
community and the gstreamer.freedsktop.org community and contacted the
wrong people, I don’t know. But anyway: so far my mods haven’t seen wide
