This may be related to issue #96.

I've been using a patched egg of a package from git, and now I want to test a mainline version in a copy of my virtualenv:

```
$ cpvirtualenv develop mainline
$ pip install --upgrade mypackage
```

This downloads the new version of the package, but `pip freeze` reveals that it's still using the `-e` version of the package. So I tried uninstall and got an error:

```
$ pip uninstall mypackage
Not uninstalling mypackage at /Users/dan/.virtualenvs/develop/src/mypackage-deva, outside environment /Users/dan/.virtualenvs/mainline
```

Using pip 1.0.2 and virtualenvwrapper 1.7.
