Okay, I did the following to avoid this:

import sys, os.path
modulepath = os.path.abspath(os.path.dirname(sys.argv[0]))
def import_local_module(name):
    """Load a module from the local modules directory.

    Loading e.g. a local "parser" module is difficult because on
    Windows, the stdlib parser module is a built-in and thus loaded
    with higher priority.  With
    http://www.python.org/dev/peps/pep-0328/ it may become simpler.

    :Parameters:
      - `name`: name of the module, as it would be given to
        ``import``.

    :Return:
      the module object or ``None`` if none was found

    :rtype:
      module
    """
    import imp
    try:
        return sys.modules[name]
    except KeyError:
        pass
    fp, pathname, description = imp.find_module(name, [modulepath])
    try:
        return imp.load_module(name, fp, pathname, description)
    finally:
        # Since we may exit via an exception, close fp explicitly.
        if fp:
            fp.close()

Tschö,
Torsten.
