I do have MacPorts, but the error was appearing long before I installed
MacPorts, so I don't believe that is affecting anything involving the
gdi32.dll error.
Also updating to XQuartz 2.3.2.1 does not fix the problem.
I tried darwine 1.1.9 from http://www.kronenberg.org/darwine/
and also http://www.thisismyinter.net version 1.1.11.
So: any solution hints?
