Is the maintainer for net-p2p/litecoind still active? It has been quite some time now.
I've only taken the litecoin package to prevent them from being cleaned from the portage tree. I don't have enough time at the moment to test new ebuild. Please feel free to add yourself to the maintainer list or submit patched/ebuild.
does a simple bump work for you?
If bug 595452 is not fixed (presumably by this bump) very soon this is in danger of being treecleaned again.
