[Distutils] How to best install pkg_resources?

[Arve Knudsen]

I found out how to solve it; I need to
call setuptools.command.install.install.do_egg_install,
since setuptools.command.install.install.run will emulate the standard
distutils behaviour unless it's run directly from setup.py :( This behaviour
was hardly obvious I have to say :(
