Thanks for the tip Stuart.

If I'm reading the configure.in file right, the krb5-config check isn't
conditional on anything.

It also appears that this has been around for a while:
	http://mail.gnome.org/archives/gnome-vfs-list/2005-August/msg00021.html

It seems that the proper thing to do would be for kerberos to use pkgconfig,
where these problems have already been solved, but barring that, the attached
patch to gnome-vfs should add support for the --disable-kerberos flag.

The spec file will also need an update to add the flag:

-./configure --prefix=%{_prefix} --host=$CFGHOST --build=%{_build} 
--disable-openssl --disable-gtk-doc
+./configure --prefix=%{_prefix} --host=$CFGHOST --build=%{_build} 
--disable-openssl --disable-gtk-doc --disable-kerberos
