Hello, I guess i've found a small bug in distutils 0.8. sample3/setup.py shows how to extend the build command. Besides the missing function 'run_peer' in the Build class, it tries to load Build from command.build. I guess it should import command.build.build instead Greetings Berthold -- email: hoel@GermanLloyd.org ) ( C[_] These opinions might be mine, but never those of my employer.
