[Answered ]-Heroku Django app development on Windows

You can use Cygwin and install all the dependencies, but I went through that issue last week and then I realized it was far easier to use a Virtual Box with Ubuntu as my Guest OS. I still did the development on Windows but used Ubuntu just to communicate/push to heroku

I found the answer to my problem. I believe the problem is that pip is looking to compile the dependency from source. The solution is to find a link to pre-compiled version of the dependency. You can then pass this link to the easyinstall library installed in your virtualenv. Easyinstall will download and install the pre-compiled version of the dependency.
