So what is up with the "Requires.private" entries in various pkgconfig .pc files ? Most mock fc5 builds are currently failing because of a missing dependency between libX11-devel and libxau-devel. Culprit seems to be : bash-3.00# grep -i requires /usr/lib/pkgconfig/x11.pc Requires: xproto kbproto inputproto Requires.private: xau xdmcp -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
