PostgreSQL - Problem installing gem

Hi fellas!

I was trying for a few days to solve a problem installing pg gem.

The error was about this freaking file: libpq-fe.h

The solution was to uninstall all my postgresql and install these two packages:

$ sudo apt-get install postgresql-9.1
$ sudo apt-get install postgresql-server-dev-9.1

Then you can install your gem with easy.

$ gem install pg

Adios!
