The reason? File incorrectly named. !!! Couldn't download 'Theme-TuxInfo-Connectiva.tar.bz2'. Aborting. In http://distfiles.gentoo.org/distfiles, it's called "Theme-TuxInfo-Conectiva.tar.bz2" Notice the missing n. Can you please add the n into the file name on the distfiles site?
I actually had to remove the reference to the tarball with double 'n', as that's what upstream calls it. It's fixed in CVS now.
