wxPython could be considered the only GUI option - there is the TclTk GUI still in GRASS 6.4, but I don't think it's kept up to date now, and it is not in GRASS 7.
Is there a reason for using your custom /opt/local Python for GRASS? I don't think the older system Python 2.6 version is a problem for the GUI. If you are using the /opt/local Python unintentionally, probably what is happening is that it (or MacPorts) added something to your shell init (.bash_profile) to add /opt/local/bin to your PATH. GRASS then picks this up and uses the Python it finds there. You can get around this by adding a line to your .bash_profile: export GRASS_PYTHON=/usr/bin/python2.6 On Aug 12, 2011, at 11:20 AM, wagner wrote: > Is this the only possibility to use a GUI an OS X? > > > Am 12.08.2011 um 18:05 schrieb William Kyngesburye: > >> It won't work 64bit - wxPython 2.8 (included in the GRASS package) can't be >> built 64bit on OS X. >> >> On Aug 12, 2011, at 9:02 AM, wagner wrote: >> >>> Hello, >>> >>> I tried to install GRASS with GUI on my Mac with Mac OS 10.6.6 (Snow >>> Leopard) 64 Bit, but I always got the following message while starting: >>> >>> arch: posix_spawnp: /opt/local/bin/pythonw2.6: Bad CPU type in executable >>> >>> I loaded it from http://www.kyngchaos.com/software/grass and as well all >>> the required packages. >>> >>> I hope that anyone has a solution for that. >>> >>> Kind regards, ----- William Kyngesburye <kyngchaos*at*kyngchaos*dot*com> http://www.kyngchaos.com/ "Time is an illusion - lunchtime doubly so." - Ford Prefect _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
