[Distutils] setuptools and picard

Hello I'm trying to install picard (http://musicbrainz.org/wd/PicardDownload) with python -c "import setuptools;execfile('setup.py')" install --single-version-externally-managed --root=/path/to/root but it breaks with: usage: -c [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: -c --help [cmd1 cmd2 ...] or: -c --help-commands or: -c cmd --help error: option --single-version-externally-managed not recognized Is that ok and i should use ./setup.py without "import setuptools;execfile('setup.py')" hack, or if this a bug in setuptools that should be fixed? PS: I use setuptools 0.6b3 -- Pavel
