Proposed solution is to install two packages via Linux package management:
sudo apt-get install libpq-dev python-dev

This is in general possible. But, same as with #16, I would love to how a solution that is in-line with capabilities of pip. Does anyone know how I can tell pip to install the above package via system package management and this favorably platform independent?
