Hrm, I think it's because the specfile installs itself in /usr. Hrm, but
LTTV uses these paths as default in the application, so we don't wan't
to change them into something like %{BuildRoot}/usr...

Can you try creating the packages in a chroot or something like that ?

Otherwise we would have to figure out how to specify different paths
within LTTV and for build.. it might be cleaner, but it's not trivial.
