--- Comment #10 from jeremy.fergason@gmail.com --- I've cleaned up a lot of the comments from Dave Johansen in the spec file. Swift doesn't like to play well in the /usr/lib64 directory ... /usr/lib is hardcoded in a number of places. I'm looking at ways to fix this as %{_libdir} is %{prefix}/lib64 on multiline systems.
