A typical install of OS X won't create a .bash_profile for you. When you want to run functions from your command line, this is a must-have.

Start up Terminal
Type "cd ~/" to go to your home folder
Type "touch .bash_profile" to create your new file.
Edit .bash_profile with your favorite editor (or you can just type "open -e .bash_profile" to open it in TextEdit.
Type ". .bash_profile" to reload .bash_profile and update any functions you add.
