muwlgrJust a couple of notes to remember :
1. When you upgrade your Trac module, easy_install --upgrade Trac is often not enough. You have to check and remove all traces of older Trac versions from site-packages directory. Installation of older Tracs created site-packages/trac directory which has to be removed by your own hands. Together with other Trac*egg files and directories. Or else you have a chance to get into delusion that you are using newer Trac, while really you are still using older one or even worse, a mix of older and newer. "Database newer than Trac version" is a symptom of this kind.
2. mod_python 3.x is still unable to import modules from .zipped .egg-files. Command-line python (even older version 2.4 which is included into RHEL5/CentOS5) imports modules from zipped eggs without any problem, but not mod_python for the same version because it overrides the standard importer in its own special way. So with command-line python you can easily import 'trac' and all required submodules, but mod_python will tell you that there is no module named 'trac'. The solution is found to be: easy_install --always_unzip Trac
Yeah, that's reality of the opensource : you really get what you have paid for :>
