This is something I’ve wanted for quite some time: the new style Last.fm plugin takes Last.fm integration to Rhythmbox. Download here. You can install it by following these steps:
1. Add PORTDIR_OVERLAY=”/usr/local/portage/” to your make.conf
2. Run ‘mkdir -p /usr/local/portage’
3. Download the ebuild package from the link above and unpack it: tar xvjf new-style-lastfm-ebuild.tar.bz2 -C /usr/local/portage/
4. Emerging rhythmbox as you normally would.
And that should be it. Also, as the author of the patch writes, remember to only have one of the Last.fm plugins enabled at any time.
