Re: [Gtk-osx-users] PyGTK on top of native GTK+?

OK, so I have run jhbuild, and I now have a working version of GIMP 
running on native GTK+. Couple of obvious bugs: command-Z for undo 
doesn't seem to work... something wrong with the keybindings, it seems. 
Also, the usual mouse-wheel zooming seems to be broken too.

What's next for getting PyGTK running? Do I have to tell jhbuild to do 
something, or do I download a separate tarball and build it manually?

The key thing is that the dependency system of jhbuild works correctly. 
So I don't see why you would want to hide the module from the user.

That would appear to be poor packaging practice, to me, rather than a 
fault of these package managers intrinsically, don't you think? 
Obviously there are some challenges to putting a package manager on top 
of an operating system that doesn't itself use one, but I think it can 
be managed. At least one should aim for a modular set of binaries that 
new developers can download in order to get started on a new machine.

Yes, that's a different philosophy, I guess. User-centric, because you 
need to have a single download-and-install package for them, because 
that's what they expect on that platform. But I think that a package 
manager is the more elegant solution both for user and for developer.

OK. I'll look into it.

There has *got* to be a better solution than requiring every GTK-OSX 
developer to build their whole GTK+ environment from source. I thought 
that better solution was fink (apt-get) or Macports. But if it's not 
(certainly, I was surprised at how poorly maintained the binaries for 
fink are), then perhaps just a big whopper tarball of GTK+ for both 
Python and C users isn't so bad...?
