BTW: Redmine package:
https://bugzilla.redhat.com/show_bug.cgi?id=499959
Redmine is apparently going to be installed into %{_datadir}. The only
difference is how was the original source obtained. For deltacloud-core
it is gem while for redmine it is tar.gz, but at the end, it could be
zip or whatever else, it is just archive.
