I am unable to use nose (nosetests) in a virtualenv project - it can't seem to find the packages installed in the virtualenv environment.

The odd thing is that i can set

```
test_suite = 'nose.collector'

```

in setup.py and run the tests just fine as

```
python setup.py test

```

but when running nosetests straight, there are all sorts of import errors.

I've tried it with both a system-wide installation of nose and a virtualenv nose package and no luck.

Any thoughts?

Thanks!!
