The Hivelogic page has been indispensible when setting up my Mac for development. The one thing that it does not mention is how to tweak your man configuration so that you can see the manual pages for the software you have just installed into /usr/local.
The configuration file for man is in /usr/share/misc/man.conf by default. You can type man man to confirm this. Edit the file as root and add a new MANPATH setting pointing to /usr/local. Simple!
MANPATH /usr/local/man
