I didn't say it's needed. I said that he should try that, perhaps it helps. > One thing we noticed (I'm not sure has this been yet submitted to > bugs.python.org yet) was that installing packages created with Python > 2.5 to Python 2.6 failed unless Python was in %PATH% [1]. In general, that's not supported at all. You will have to rebuild all packages for Python 2.6, unless they are pure-python packages (in which case PATH should be irrelevant). If the .pyd files would have loaded, Python would have complained that they originate from the wrong Python version. > Another pretty severe problem was that installers created with Python > 2.6 didn't work at all with older versions [2]. That's not a bug, either. It has been that way since Python 1.4 or so: .pyd files built for X.Y won't work for X.(Y+1), and vice versa. It seems that you mean something specific with the word "installer"; I think you should elaborate what precisely you are referring to.
