Hello, It seems that the new version is 0.11.1: https://github.com/manastech/crystal/releases Please, if possible, update it.
@Renich I've email the proxy maint about this package, if you're interested in this package maybe you can take over the maintenance if he's not interested or co-maintain with him, what do you think?
@Tomáš I have, just, stated to maintain a package in my own overlay. I am a newbie. I could try it out. Let me read the guidelines and dev guide and... sure, why not?
@Renich, sure, take your time ;) When you have a working ebuild, post it either here or even better open up a pull request on github and visit proxy-maint @irc.
Sorry for the late update. I've post a pr for the latest crystal. https://github.com/gentoo/gentoo/pull/732
