expansion error on multiple BuildRequires

Hi, When using multiple BuildRequires for different distributions like ------- %if %{suse_version} > 1000 BuildRequires: qt3-devel kdelibs3-devel %endif %if %{fedora_version} > 1 BuildRequires: qt-devel kdelibs-devel %endif ------- i always get "expansion error" for all distributions. is this a know issue or can this be fixed in any way? The same spec files works without a problem when building outside of the build service. BTW : it would be nice to know some details about the "expansion error". see https://bugzilla.novell.com/show_bug.cgi?id=154055 Regards, Stefan
