Ah I see, this makes sense. How well the GUI tests run seems rather
inconsistent. I think there might be an alignment issue that's causing
so many of the GTK3 tests to fail.

I've already added the libraries to PATH when building, but thanks for
the suggestion. I did also have to remove the system wxwidgets install
even with that, because the unit tests kept trying to use that,
resulting in fork errors and other unpredictable behaviour. Any more
ideas? Honestly, I'm happy to test manually with the wxPython demo and
some wxwidgets test programs if that's considered good enough.

Another interesting thing is that I get the following messages when
running cygport install:

Warning: x was not linked with -Wl, --enable-auto-image-base

Is this anything to be alarmed about or not really an issue? The
libraries seem to work okay, at any rate.
