simohe <simohe at besonet.ch> added the comment:
fix_imports rewrites the import statements to local or global. When a python module loads a local extension module, this import statement should be converted to a local import (from . import extensionmodule). But when the extension module is not built yet, fix_imports does not find them (no file named extenstionmodule.[so|sl]). So it suggests a global import (import extensionmodule).
The original comment is a slightly modified version of this here:
http://selenic.com/hg/file/afc02adf4ded/contrib/setup3k.py#l223
short summary:
build.sub_commands in distutils.command.build should list "build_ext" before "build_py".
lib2to3.fixes.fix_import will write global instead of local import statements else.
