I attach the updated ebuild for version 3.76 of xawtv. It requires make >=3.79.2* (see bug# 7343). I didn't adapt the deinterlace patch to this new version. It had only two rejects, one trivial, the other one a little more complex (not that much anyway), and since I am facing some problems with my bttv card ATM, I left it for later. You can modify it :) Oh, in this ebuild I commented out the installation of the webcam.cgi, because I haven't used it and I didn't like the installation path (/usr/local/httpd/cgi-bin), which was empty on my system and AFAIR when I had some web server it was somewhere under /var. I am not sure about how this should be, though.
Javier, where's the attachment?
