+- Add alsa-devel BuildRequires: we care for ALSA support to be
+  built and thus need to ensure we get the dependencies in place.
+  In the past, alsa-devel was pulled in by accident: we
+  buildrequire libgnome-devel. This required esound-devel and that
+  in turn pulled in alsa-devel for us. libgnome is being fixed to
+  no longer require esound-devel.
