I did not use that script.

This is the wxPython version that worked for me as well, IIRC I also saw th=

installation errors and suffered no ill effects from them.

I mentioned needing a different wxPython version for one of the two systems=

Here are some details. The first system ran fine with (please ignore mangle=

Setting DYLD_LIBRARY_PATH was causing some external libraries to stop worki=

According to my notes "installing gtk+2 breaks wxPython" I believe that thi=

was later tracked down to the issue noted above. IE I had gazebo working=20
without ground textures until I installed gtk2 and then gazebo would crash.

You will need gdal whether it is available from fink or has to be installed=

hand I do not know, this was not a requirement of mine.

I did not need to alter any OpenGL settings or parameters.

Please note that while I was able to get everything running there was some=

weirdness with the control windows not being able to be moved from the uppe=

be moved but the interface control windows got stacked in the upper left=20

Hope something in here helps.
