Comment 1 for bug 369234

Bug seems related to the install path in site-packages. Please check if the sendoff.egg is in the 2.5 or 2.6 packages dir.

If it's in the 2.5, it might not be in the path of your current python and needs to either removed/reinstalled to go into 2.6 or moved and the bin in /usr/bin/sendoff to point to the right path.
