I installed PG on Mac OS X via Homebrew (I didn't realize it came default in Mac OS X), and had the same problem. I may have made the problem worse by installing the pg gem before installing pg via Homebrew.

I solved this same problem by doing the following:

1. Make sure that all binaries are pointing to binaries in Cellar directory (/usr/local/Cellar on Mac OS X)
2. Uninstall pg gem gem uninstall pg
3. Reinstall with Homebrew configs gem install pg -- --with-pg-config=/usr/local/bin/pg_config (if you created a rails project with pg setup, this is explained in your database.yml config file)

And it worked!
