My understanding is that psycopg2 looks for some postgres files during the install. If you have postgres already installed on the same box, you should be able to resolve this problem by adding the postgres folder to your PATH environment variable before running 'pip install psycopg2'. The syntax for modifying the PATH might differ a little based on the operating system, but it would normally be something like this:
PATH=$PATH:/Library/PostgreSQL/9.1/bin Here postgres is installed at /Library/PostgreSQL/9.1/bin, but it might be in a different location on your machine. As Fabio mentioned, if you do not have postgres installed on the same machine you may be able to add the development libraries for your OS and get it to work. One note about modifying the PATH - due to the way virtualenv can adjust PATH contents you may need to add the postgres folder to the PATH after the virtualenv is activated. (not sure about this ...) Hope that helps!
