The quite old surfer plugin doesn't have an ebuild up to now...
Created attachment 190844 [details] New ebuild Complains about conversion to gettext and textrels - not sure what that is about.
looks like the plugin is not mainted anymore the, in the sources, precompiled libvdr-surfer.so is for vdr.1.3.24 this will say all :) (still waiting in near future for vdr-1.8,x) also, vdr-team is to busy to fix the textrel/gettext things seems so, the plugin is written with a hot needle ;)
plugin is dead src_uri is dead no new versions from upstream
