I installed GRASS on my new computer from this page a week or so ago. http://www.kyngchaos.com/software:grass/ > > If you are not using a recently compiled binary (after mid-September), you > will have problems. > > My guess is that this is related to ticket: > http://trac.osgeo.org/grass/ticket/753.

Or Indeed! I have no idea how to find these files and I fear that I will really mess something up here. > 2) bundle wxpython with GRASS. Unfortunately I don't know how to do this. On the page I listed above it says that wxpython is included in the GRASS install. I didn't think that I was using the Python GUI but perhaps I am misunderstanding something here. When I open GRASS I hit return to load the GUI I don't run "g.gui wxpython". Is there an idiots guide to on how to bundle wxpython? > The second option guarantees that you are running with the version of > wxpython that you compiled with and that all parts of GRASS are using the > same wxpython.
