[Distutils] setuptools and picard

[Pavel Volkovitskiy]

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
