--- Comment #28 from Robin Lee robinlee.sysu@gmail.com --- LICENSE would be included in three packages. That's conflicting and will leave the %{_defaultdocdir}/%{name}-%{version}/ directory unowned if wt is not installed. There are two solutions:
1. Let wt-dbo and wt-doc have their own doc dir. For wt-doc that is %{_docdir}/%{name}-doc-%{version}/, so wt-dbo and wt-doc can include their own true copies of license.
2. Let wt-doc require wt. But it's not acceptable if wt-dbo requires wt.
