pg gem on OS X

Building pg gem on OS X Snow Leopard

After PostgreSQL has been installed with ports, pg_config and other tools can be found in "/opt/local/lib/postgresql84/bin". Add this path to $PATH and set ARCHFLAGS="-arch x86_64".

These can be set within the same command line when installing the gem:

PATH=${PATH}:/opt/local/lib/postgresql84/bin ARCHFLAGS="-arch x86_64" gem install pg

They can also be set in their own right:

export PATH=${PATH}:/opt/local/lib/postgresl84/bin
export ARCHFLAGS="-arch x86_64"
