Cannot install wheel from local file system if name not all lowercase on Windows

[daybarr]

Using buildout.wheel 0.2.0 with zc.buildout 2.9.3, github bash on Windows 10.

Steps to reproduce follow.

First Prepare a buildout.cfg in empty directory, bootstrap buildout into a new virtualenv, download the Django wheel to local directory.

Now try to buildout install (-U to be sure I'm not using my user prefs (cache etc)):

Observe that this work ok when wheel is downloaded from an index server

It seems that we have to be installing directly from local file system (thanks to find_links = . in the buildout.cfg) to hit the bug.
