[Distutils] distutils version numbering

hi there, I'm writing a custom 'build_scripts' command that works around a bug in earlier versions of distutils, i.e. it makes scripts executable on posix platforms after they got copied to the build_dir. I'm looking for a discriminator that allows me to decide whether or not to run the code, depending on whether the distutils version requires it. It seems the version coming with python 2.2 requires it, while python 2.3 and up don't. However, distutils.__version__ for python 2.2 as well as python 2.3 are the same ('1.0.3') ! Am I just looking in the wrong place ? Thanks, Stefan
