 Replying to [comment:6 kobayos@…]:
 > I experienced the same problem on Mountain Lion with MacPorts 2.1.3 and
 XCode 4.6.2
 > Although I have not checked whether it correctly works or not, I could
 build successfully by applying a patch that was provided at the upstream
 bug report : http://trac.osgeo.org/grass/ticket/1843

 > Please check the difference of the Portfile and the patch file.

 Yes, that resolves the error with TkCopyAndGlobalEval, but the python
