I installed the wrong version of pysvn in my system using the .dmg. I realized the mistake and removed the pysvn folder from /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/. I don't see pysvn anywhere else on my system.
Now when I try to install the correct (older) version of pysvn the installation process stops with the message "A newer version of pysvn is already installed." Where else do I need to remove the previous installation of pysvn?
