Your eclass inherits base.eclass. For several reasons, we at the QA team would like to remove base, and so we ask that you remove the inherit. See bug 497022 for notes on transitioning your eclass away from the base inherit and checking for problems that could crop up.
i will not fix this, what i will do, is move all depending .ebuilds to use the newer vdr-plugin-2.eclass in the near future (there are only a handful left in the tree) vdr-plugin.eclass is internal marked as deprcated on use with .ebuilds after changes in .ebuild finaly i will remove the vdr-plugin.eclass from the tree
