After a breaking my head of why 0.30 does't work with gDesklets-core-0.30 I created an ebuild for a 0.31 which "works with .30" (taken from a starterbars' Changelog).
Created attachment 41745 [details] a little bit tweaked ebuild script
Created attachment 41746 [details] digest file - in this version file is gz not bz2
Also, as probably already known, the upgrade from 0.26x will require manual creation of ~/.gdesklets/Sensors folder.
Yeh, I've got this locally, and I'll add it along with gdesklets-0.31.1 as soon as the new python libraries (pyorbit, gnome-python) are in from the python team.
Added now.
