I just rebuilt nicotine and will upload in a moment, but I noticed something that we need to do in order for python apps to work smoothly in the case of both versions of python being in the system at one time. The python scripts that launch apps such as nicotine need their shebang to point to the right version of python and not just /usr/local/bin/python as they do by default. Depending on the version of python the app uses, the line should read:
#!/usr/local/bin/python2.6 for the current python
#!/usr/local/bin/python2.5 for python-2.5.2
The symlink /usr/local/bin/python will use the version of python that gets installed first, so it is not what needs to get invoked.
I can go through the apps and see what needs to be adjusted and make the adjustments.
