Getting gtk3 and all its dependencies installed is of great help. So
MacPorts did help.

This is exactly what I did yesterday but I didn't had the time to
email my results. I know have perl-Gtk3 working under OS X :) Here's
what I did:

First install MacPorts, i followed the instructions from their web
site [1] and I downloaded the dmg installer and executed:

sudo port -v selfupdate

The set your environment properly, add this to your shell and your
~/.bash_profile

export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
export MANPATH="/opt/local/share/man:$MANPATH"
export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
export LD_LIBRARY_PATH=/opt/local/lib
export GI_TYPELIB_PATH=/opt/local/lib/girepository-1.0

If you change your default ports folder you're on your own and you
should be able to figure out what to change (replace /opt/local with
your port's installation folder).

Now the fun begins. Installing gtk3 is as easy as:

sudo port install gtk3

The problem is that gtk3 and a few libraries are compiled without
introspection. Fire up your editor skills because we need to edit a
few files. You'll find the files here:

cd /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports

sudo nano -w gnome/gtk3/Portfile
sudo nano -w graphics/gdk-pixbuf2/Portfile
sudo nano -w x11/pango/Portfile
sudo nano -w devel/atk/Portfile

Look for the word introspection and replace the flag with
--enable-introspection. Then uninstall and reinstall these ports:

sudo port -f uninstall gdk-pixbuf2 && sudo port install gdk-pixbuf2
sudo port -f uninstall pango && sudo port install pango
sudo port -f uninstall atk && sudo port install atk
sudo port -f uninstall gtk3 && sudo port install gkt3

If I didn't forget a single command then gtk3 would be built and
installed with introspection support.

Installing perl-Gtk3 is now an easier task since all that's needed is
to install the introspection library:

sudo port install gobject-introspection

That's it the rest should be a normal CPAN installation procedure.

I still have to try compile WebKitGtk+'s port with gtk3 and
introspection. I haven't even tried this step yet.

I hope that this helps someone else.
