Ahh, that explains why I couldn't figure out the problem when inspecting the code for MacPorts - I was looking at HEAD, not at the release version I had installed.

This port depends on code available in HEAD that haven't been ported to the release branch (and that basically uses ruby gem to download files). Last time we talked about releasing a new version of MacPorts, we were looking for the notes James wrote about this upgrade process and that were lost with the darwinports to macports transition.
