Please check whether the use of 'einstall' in this ebuild is actually needed. From a quick glance at the Makefile, it seems to have proper support for DESTDIR. Therefore, if possible please replace the call to 'einstall' with proper 'default' or 'emake DESTDIR="${D}" install'. Thanks.
This bug can be closed, the corresponding ebuild is not in the tree any more. Next version media-video/vdr-2.0.6-r1 does not use 'einstall' I have no access rights to close this bug.
