Missing dependency `pkg_resources` if installed without pip

Hi.
I just noticed that punq doesn't depend on pkg_resources explicitly. The only thing that hints at this is recommended way of installation using pip.

I think this may have been fixed by the toolchain refresh. Can you confirm on 0.7.1.dev1?
