Ah, that is totally my bad, I added that in to detect if port was installed
while I was working on the
Homebrew<http://www.ros.org/wiki/electric/Installation/OSX/Homebrew>port.
I forgot that port goes into 'interactive' mode if you don't give it
a verb.  `port help` is a good alternative or `port --version`, just
anything that tests to see if it exists and is in the path.

When you file the ticket let us know here.

Thanks,
