Thank you for your contribution. I had a short look on the ebuild. 
Here a few ideas:

• Please test the ebuild with repoman full -x
• you can use SRC_URI="mirror://github/... 
• which GPL?
• please fix the header. (see /usr/portage/skel.ebuild and

...and eutils is not required anymore in EAPI=6 for your needs

A better ebuild for -9999 and -0.2
Comment 4 Philippe Trottier 2018-04-04 00:44:33 UTC
The GPL is GPL-2 or above as stated in the header of his rtl_ais.c file.

Thanks Philippe for your contribution. Are you willing to proxy maintain this package? I personally am not very interested in it, but I'd add it if you would take of it in the future.
Comment 6 Philippe Trottier 2018-05-03 11:56:27 UTC
Hello Marc, I would be happy to take care of this package. 

I plan on using it a lot with my sail boat. I am guessing the opencpn crowd might be interested in it too and more willing to keep it in sync. 

I guess I'll have to create a Gentoo Opencpn wiki somewhere. If I wasn't unsure about the next few months and access to IT ressources while sailing in Greenland, I'd even ask to get back in the dev gang. But for now, I may have to be a vagabond for a while.

New ebuild 0.3 and 9999

Small update for rtl-ais to make it work properly with opencpn-plugin-rtlsdr

Hi Philippe, sorry, this bug got totally out of my mind. Are you still around and still would update/maintain it?
