How to install pg (postgresql) gem on Snow Leopard, 64 bit

Posted on August 20, 2009 by kain

Install PostgreSQL from source/port for this, does not currently build against binary package.
PATH should be /usr/local/pgsql.

export PATH=/usr/local/pgsql/bin:${PATH}
env ARCHFLAGS="-arch x86_64" gem install pg

Or if you are using macports:

export PATH=/opt/local/lib/postgresql83/bin:${PATH}
env ARCHFLAGS="-arch x86_64" gem install pg

This works also if you have installed postgresql via mac ports, just ignore the export PATH

Thanks for this. Forgot that it was -arch x86_64 not -arch i386.
