dbus-sharp-glib-0.5.0-bp154.2.55

- fix libexecdir. mono can't use libexecdir because /usr/lib
  is fixed in pkgconfig

- Removed %clean section.

- Spec cleanups:
  + Minor cleanups on syntax and improved comments.
  + Use pkgconfig() calls for >= 1130.
  + For <= 1110 added %{_libexecdir} and replaced %make_install
    method.
  + Enabled parallel builds (tested ok).
  + Removed nuking of buildroot on %clean.

- Initial package, based on the ndesk-dbus-glib package from the
  Mono OBS project
