Trying to install psycopg2 on OSX results in the following:

Does anyone have any idea what can I do to get it installed? I have Postgres installed and it seems to work fine.

I’ve tried both easy_install and pip install, but both end up with a similar message.

There is something wrong with your ARCHFLAGS actually sticking, try using this:

sudo env ARCHFLAGS="-arch i386 -arch x86_64" pip install psycopg2
