The mobile-broadband-provider-info package doesn't include the pkgconfig file which stops network-manager-netbook from compiling as the configure script can't detect it. See the following build for details. http://koji.fedoraproject.org/koji/getfile?taskID=1473608&name=build.log
Ping. network-manager-netbook won't compile without it which makes moblin quite useless without network support :-( Can you provide a devel package with just the pkgconfig file, or a possible work around?
