Django project at Heroku cannot install dependencies with pip

i'm trying to deploy a django project on Heroku. I use virtualenv and pip to manage dependencies. The virtualenv version is 1.7.1 and pip that comes with it it's 1.1. I tried to force the --no-site-packages but it prompts that it's the default behavior now. Also i'm sure that i install everything within the virtual environment. The django project it's empty. I followed the instructions here . Maybe the problem it's that their versions of pip and virtualenv are older? Has anyone encountered this problem? Thank you in advance.

ψ pip.exe freeze
Django==1.3.1
distribute==0.6.24
versiontools==1.8.3
(venv)

ψ more .\requirements.txt
Django==1.3.1
distribute==0.6.24
versiontools==1.8.3

(venv)

ψ git push heroku master

It seems that the problem it is in the requirements.txt, i created it using powershell and "pip.exe freeze > requirements.txt" command, which creates a file with a name that has nullbytes in it. I was able to get around this problem by downloading a requirements.txt from an example project on github and modifying it. That did the job and everything works nice.
