The current EPEL7 package does not provide the -x11 subpackages. This was due to a missing dependency in RHEL7. With RHEL 7.2 this package is now provided and therefore we should package the x11 components too. I tried to checkout the master and just recompile it for EL7 and I was successful doing so [0]. This should be a 5 minutes work :) [0] https://copr.fedorainfracloud.org/coprs/fale/i3/build/317881/
I've requested the ACL so I can help with this :)
I just pushed 0.6.1 to epel7 - is this good enough? https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2016-e49e9b8b06
Perfect, thanks :)
