Requires: %{orig_name}% = %{version} Requires: %{orig_name}% >= %{version}-%{release}
You probably don't want to specifically do "Requires: %orig_name >= %version-%release" there, as it's quite likely that will have unintended consequences as this package gets updated out of band.
You probably want a Conflicts stanza:
Conflicts: %{orig_name} < 0.1.8-12
That way, this doesn't break if the release goes out of sync.
