I assume you're talking about http://marcoschuh.de/wp/?page_id=411 --
I took a look at it and it seems to do roughly the same things I did
(except without ifdefs for non-OS X).

There isn't any automatic support for OS X menus in GTK3 either, so
unfortunately there needs to be ifdef'd sections for proper OS X
support -- the application can build without the optional menu
support, but just looks really out of place on OS X.

There's a function in `GtkosxApplication` called
`gtk_osxapplication_set_use_quartz_accelerators` that implies that it
would fix the shortcuts appropriately -- but doesn't, so I don't
believe gtk-mac-integration has support for modifying key bindings
automatically.

The GTK dependencies were all pulled in from jhbuild and the libraries
for media files (libogg, libid3tag etc.) were from Brew. There doesn't
seem to be any problem with linking libraries in both places and, when
bundling, gtk-mac-bundler pulls libraries from both locations into the
app bundle.

Building for GTK3 on OS X is painful and requires a lot of fiddling
around with dependencies and patches for installing
gnome-themes-standard so users aren't stuck with Raleigh, but when
better support for GTK3 in jhbuild arrives, it should build fairly
painlessly.

Cheers,
Tony
