If you could write bullet points for doing this, I'd be happy to expand
it with screenshots etc. If you don't have a wiki, then maybe we could
make a start here (on a new page linked from)...

It sounds to me as though ige-mac-integration could perhaps be split
into two separate packages, if that is the case. Having to build a
package twice is highly irregular, and will fox most developers, I'd say.

I'd like to know why you think that way and fink/macports packaging. Is
there a reason why you'd rather they didin't? What's the philosophy
mismatch? I personally love being able to just type "apt-get install
whatever" and have all the dependencies installed automatically.

Do you have any details on how to build macports apps with Quartz
instead of X11?

If there are problems with the frameworks thing, then perhaps it could
be useful to just provide a binary tarball of GTK+ (with a working
pkg-config script) as provided for GTK+ on Windows?
