My testing indicates that pkg_resources works ok.

I am writing a package manager gui. I don't have a project.

If there are projects or things like that, I tell the user to go
get zc.buildout or pip.

I am driving easy_install..

Seems to work reasonably well in many cases....

That isn't a typical use case in my scenario.

A typical user just wants to install package x,y and z from
pypi. They want them to go "into python" and it is as simple
as that. Those packages will probably end up in site-packages
but as likely as not, the user won't care where they go as
long as they are available when they are needed.

When they are finished, or they don't like them.. they want
to deinstall them by clicking the remove button.

In what I am doing, the nested directories would have been
happily removed.

I appreciate your feedback and it is nice discussing these
things with you.

Best Regards
