Please do a binNMU for unicap on sparc. Right now, the unicap libraries and -dev packages are uninstallable on sparc because it depends on an unavailable version of the ffmpeg-debian libraries, due to a bug that was in ffmpeg-debian. This bug has been resolved with ffmpeg-debian-4:0.5+svn20090420-2. See bug #527350. -- Regards, Andres
