Thanks for the fresh ebuild. There's a couple small issues though. The ivtv-0.1.9-r4 ebuild has ptune.pl removed, but not the README.ptune. ptune.pl has been removed, but no alternative ebuild has been submitted (at least that I can find.)
I just committed a fix to not install README.ptune, but I'm not going to bump the ebuild for something that trivial. I'm still working on an ebuild to install the ptune stuff. I'll get to it when I can.
This include record-v4l2.pl? That appears to go uninstalled from the ebuild too.
