This works for me with snapshot-2014-12 on OSX.  I can type into the
window, but hemlock is sufficiently different from emacs that I can't
really do anything useful with it.

That's because you need to do (require :clm).  (Don't ask me why it's
clm. I don't know).  Then (interface:lisp-control-panel) brings up an
inspector panel for me.  I didn't try to use it.

There were some relatively recent fixes for motif especially if you're
running on a 64-bit system with 64-bit motif libraries.

What kind of graphical interface are you looking for?  Cmucl doesn't
really come with any specific interface.

You didn't ask, but my favorite graphical interface for lisp is emacs
with slime.  Fantastic development environment, if that's what you're
looking for.
