Unfortunately, it's not just a packaging problem.  (Well, packing of  
Haskell libraries, that is.)

There are two version of GTK+ Mac OS X: (1) the MacPorts version and  
(2) a native GTK+ framework.

Unfortunately, both are not satisfactory.  The MacPorts version is  
based on X windows, which is supported on Macs right out of the box,  
but to be honest, X programs on the Mac are ugly and annoying.   
Moreover, whether the MacPorts version builds at all seems to be a  
matter of luck - I have been out of luck more than once.  MacPorts is  
also pretty useless once you want to distribute your GTK-GUI programs  
to other Mac users.

The native GTK+ framework is a port of GTK+ to the native Mac GUI and  
dead easy to install (it has a binary installer).  Unfortunately, it  
lacks many of GTK+'s optional components (most notably libglade).  It  
is however in beta right now, so we can only hope that there will be  
more of the optional components in the final version.
