IOError: [Errno 13] file not accessible after install setuptools

[coto]

I installed setuptools on my Macbook Pro Mountain Lion, and Babel with Jinja2 in order to run Babel locally.

$ sh setuptools-0.6c11-py2.7.egg --prefix=~ --install-dir=/Library/Python/2.7/site-packages/

$ easy_install babel jinja2

After install those packages, I have this warning per any request:

But after 2 minutes with any request I have this error and I have to restart the application
