Installing via pip under Win7 + virtualenv + VC++2008

Hi,

I'm trying to unify my development system (Ubuntu) with some coworkers who
are using Windows. I'm using virtualenv, and am trying to make their setup
as painless as possible.

And thus, I'd like to have them be able to install psycopg2 via pip in their
windows-based virtualenv. They have VC++ 2008 installed, Python 2.7,
setuptools, etc.

pip install psycopg2 appears to download and compile (psycopg 2.4.1) and I
get files in env/lib/site-packages/psycopg2:

3 Dir(s) 94,301,532,160 bytes free

But, when running python, I get this:

Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)]

Type "help", "copyright", "credits" or "license" for more information.
>>> import psycopg2
Traceback (most recent call last):

File "psycopg2\__init__.py", line 71, in <module>
from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: DLL load failed: The specified module could not be found.
>>>

Any debugging help would be greatly appreciated. I know I can install
win-psycopg2, but I'd rather just get the pip install working for everyone,
since it automates the install in a scriptable way.
