It seems that (at least for me) I had to type:
git clone git://github.com:jesseward/plex-lastfm-scrobbler.git
hey thanks for this. Not sure how that crept in there. The README.md on github appears correct.
I have fixed a few bugs and added some features since this initial post. Latest version can be found @ https://github.com/jesseward/plex-lastfm-scrobbler
