Gianfranco,
* Package name : rhythmbox-plugin-alternative-toolbar
Version : 0.15.0-1
I've uploaded a newer version with a new autotools build mechanism here:
http://mentors.debian.net/package/rhythmbox-plugin-alternative-toolbar
Alternatively, one can download the package with dget using this command:
In this version, the build mechanism has been completely reworked - it now uses autotools rather than the bespoke installer in the previous version.
I've tested this version via Launchpad for Ubuntu - I've kept all of your recommended Debian package specifics.
thanks
David
