Greg Benedict’s steps got me most of the way.

However, where he says that this worked for him:

sudo env ARCHFLAGS=”-arch x86_64″ gem install pg

… I had to put this in my .bashrc:

export ARCHFLAGS=’-arch x86_64′

Then run:

$ gem install pg –include dependencies

At that point I was good to go. Not sure why his suggestion didn’t work for me, but it kept giving me this error:

$ sudo env ARCHFLAGS=”-arch x86_64″ gem install pg
