How to enable dbus-X11 in the yocto - yocto

Question

I'm using poky and meta-openembedded(git://git.openembedded.org/meta-openembedded(branch: master)) in yocto
I want to build metacity and cyrus-sasl(2.1.26) for my SDK platform
I run the following command
I add BBCLASSEXTEND += " nativesdk" to metacity's bb
and run bitbake nativesdk-metacity
but I will get error message
ERROR: Nothing RPROVIDES 'nativesdk-dbus-x11' (but virtual:nativesdk:poky/meta/rec on or otherwise requires it)
ERROR: Nothing RPROVIDES 'nativesdk-dbus-x11' (but virtual:nativesdk:poky/meta/recipes-core/dbus/dbus-glib_0.110.bb RDEPENDS on or otherwise requires it) ERROR: Required build target 'nativesdk-metacity' has no buildable providers. Missing or unbuildable dependency chain was: ['nativesdk-metacity', 'nativesdk-libcanberra', 'nativesdk-pulseaudio', 'nativesdk-gconf', 'nativesdk-dbus-glib', 'nativesdk-dbus-x11']
ERROR: Nothing PROVIDES 'dbus-x11'. Close matches:
dbus RPROVIDES dbus-x11
I cannot find dbus-x11's bb in my all meta
and I cannot see dbus-x11 then run bitbake -s
How can I enable dbus-x11 ??
and...
I also add BBCLASSEXTEND += " nativesdk" to cyrus-sasl_2.1.26.bb
and bitbake nativesdk-cyrus-sasl
get error message

How can I add -lcrypt to cyrus-sasl_2.1.26.bb bb??
thanks a lot
