[libavg-users] Troubleshooting libavg installation on Snow Leopard with Python 2.6.5

[Michael Schmitz]

Dear Uli,

Thanks for the help!

With otool I found out that libavg pointed to a python version at "/System/Library/Frameworks/Python.framework/Versions/2.6/bin", where the original mac version of python (2.6.1) still was. So after adjusting my PATH such that the old binaries are used instead of the newer one, thinks work out fine again. Although I have no clue why there are 3 folders on my system with python versions (Library/Frameworks/, /System/Library/Frameworks/ and /Library/Python), I am happy things are back to normal now...

Regards and thanks again,
Michael
