Can't do anything in Terminal Due To Macports Installer Never Quitting

[Jeremy Lavergne]

> To get a working terminal so you can fix this, try changing the shell. Besides bash, OS X should come with csh, tcsh, ksh and zsh. Let us know if this lets you access a terminal window.

Another thing that might be doable is Terminal -> New Command 

This lets you avoid the existing default shell, or running your own instead.
