The gnome-config files vfsConf.sh vfspthreadConf.sh are currently in the gnome-vfs RPM, which makes configure scripts that rely on gnome-config to find installed libraries pass even though the necessary files aren't installed. Other packages have their conf files in the -devel RPM.
This defect is considered SHOULD-FIX for Fairfax.
Fixed in gnome-vfs-1.0.1-15.
