I have easy_install and pip.
I had many errors on my Linux Mint 12, I just re-installed it and I want to install everythin
This worked for me:
pip install --target=$HOME/virtualenv/ virtualenv
cd somewhere/
python $HOME/virtualenv/virtualenv.py env
. env/bin/activate
Now I can pip install whatever I want (except for everything that needs to compile stuff with gcc and has missing dependencies such as the python development libraries and Python.h).
