[opensuse-buildservice] Montone builds in OBS but has unresolved dependencies in 11.1

Hi! I was trying to install monotone from devel:/tools:/scm on openSUSE 11.1. While the package seems to build fine in the build service zypper won't install it as it has an unresolved dependency to liblua5 >= 5.1. In openSUSE 11.1 the correct package would be liblua5_1. While this seems to be an error in the spec I wonder how it is at all possible that the package successfully builds. Regards, Matthias
