Epel7 version is crucial, too.
I've been working on this one, but there were so many bundled packages (not very attractive for fedora maintaining)
which needs to be treated specifically due to https://docs.fedoraproject.org/en-US/packaging-guidelines/#bundling
It's also not preferred to have bundles, so the I've contacted the upstream, to manage this out.
There were something around 70 bundled libraries and the upstream won't change that, because it would cause them a lot of time too.
So after consideration with msuchy (my reviewer) and mschorm we've decided, not to package this one to Fedora.
