while trying to emerge the officially not yet released and masked kde 3.1, arts cannot download its source. It is looking for the non exsiting arts-1.1rc7.tar.bz2 file. I downloaded 1.1.tar.bz2 and made the digest again and it seems to work. Can somebody change the ebuild for arts 1.1? This report is just to inform you :)
this is done on purpose ... we put the ebuilds in portage so that developers and such have access to them ... until the sources are available to the public (which they currently arent), then these SRC_URI will be 'broken'
