Thanks for these instructions, John. I had to adapt to my 32-bit ghc by
adding "+universal" to the 'port install' lines. I did not find a
gtkglext.dpatch. Has it been roled into the gtkglext darcs repo? I guess
not, since the last update was Nov 7 ("Tag 0.12.0"), according to 'darcs
changes'.
Eventually everything compiled, but I get a linking error. When building an
executable, I get
Linking dist/build/TestImage/TestImage ...

Are these failures about the missing patch?
