Status of GTK+ on Mac OS X?

[John Pye <john curioussymbols com>]

Hi all

I recently did some work trying to port my program, ASCEND, for the Mac 
OS X platform. It's a GPL program using PyGTK for its GUI. I'm a regular 
Linux user, but I figured that adding OS X support could be useful for 
expanding our user base, so I got hold of a Mac and I'm trying to make 
it happen.
There's no PyGTK binary available anywhere for OS X. The only route 
seems to be to use 'jhbuild' and John Ralls' instructions from 
gtk-osx.sf.net. This seems unnecessarily difficult after the pleasant 
experience of getting started with Ubuntu and even Windows.
More generally, what level of support for the OS X platform does the 
GTK+ undertake to provide? Does the organisation have a plan to resolve 
the outstanding bugs and features in gtk-quartz?
Is there a consensus that support for OS X is valuable to the GTK+ 
community, or are more people of the view that we can take it or leave 
it? Where does this leave GTK+ compared to other GUI toolkits that offer 
cross-platform support?
Why isn't the OS X port maintained on the official GNOME/GTK website?

Cheers
