Is it possible? When installing pip, install the python packages inside my $HOME folder. (for example, I want to install mercurial, using pip, but inside $HOME instead of /usr/local)
I'm with a mac machine and just thought about this possibility, instead of "polluting" my /usr/local, I would use my $HOME instead.
PEP370 is exactly about this. Is just creating a ˜/.local and do a pip install package enough to make these packages to be installed only at my $HOME folder?

To install modules locally, you need to create and activate what is called a virtual environment, so pip install installs to the folder where that virtual environment is located, instead of globally (which may require administrator privileges).
Install the downloaded package into a local directory : python get-pip.py --user This will install pip to your local directory (. local/bin) . Now you may navigate to this directory (cd . local/bin) and then use pip or better set your $PATH variable this directory to use pip anywhere : PATH=$PATH:~/.
To do so, we can use the pip list -o or pip list --outdated command, which returns a list of packages with the version currently installed and the latest available. On the other hand, to list out all the packages that are up to date, we can use the pip list -u or pip list --uptodate command.
While you can use a virtualenv, you don't need to. The trick is passing the PEP370 --user argument to the setup.py script. With the latest version of pip, one way to do it is:
pip install --user mercurial This should result in the hg script being installed in $HOME/.local/bin/hg and the rest of the hg package in $HOME/.local/lib/pythonx.y/site-packages/.
Note, that the above is true for Python 2.6. There has been a bit of controversy among the Python core developers about what is the appropriate directory location on Mac OS X for PEP370-style user installations. In Python 2.7 and 3.2, the location on Mac OS X was changed from $HOME/.local to $HOME/Library/Python. This might change in a future release. But, for now, on 2.7 (and 3.2, if hg were supported on Python 3), the above locations will be $HOME/Library/Python/x.y/bin/hg and $HOME/Library/Python/x.y/lib/python/site-packages.

I would use virtualenv at your HOME directory.
$ sudo easy_install -U virtualenv $ cd ~ $ virtualenv . $ bin/pip ... You could then also alter ~/.(login|profile|bash_profile), whichever is right for your shell to add ~/bin to your PATH and then that pip|python|easy_install would be the one used by default.
