[yocto] gstreamer without X11?

[Gary Thomas]

I'm trying to build QTE with a distribution that does not include x11.
However, I'm getting this error:

ERROR: Nothing PROVIDES 'virtual/libx11' (but /home/local/poky-multi/meta/recipes-multimedia/gstreamer/gst-plugins-base_0.10.36.bb DEPENDS on or otherwise requires it)
ERROR: libx11-diet PROVIDES virtual/libx11 but was skipped: missing required distro feature ['x11'] (not in DISTRO_FEATURES)
ERROR: libx11 PROVIDES virtual/libx11 but was skipped: missing required distro feature ['x11'] (not in DISTRO_FEATURES)
ERROR: nativesdk-libx11 PROVIDES virtual/libx11 but was skipped: missing required distro feature ['x11'] (not in DISTRO_FEATURES)
NOTE: Runtime target 'qwt-e' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['qwt-e', 'qt4-embedded', 'gst-plugins-base', 'virtual/libx11']
ERROR: Required build target 'my-qte-image' has no buildable providers.
Missing or unbuildable dependency chain was: ['my-qte-image', 'packagegroup-core-qt4e', 'qwt-e', 'qt4-embedded', 'gst-plugins-base', 'virtual/libx11']

I don't understand why this happens though as the gst-plugins-base
recipe uses PKGCONFIG to control this:
   PACKAGECONFIG ??= "${@base_contains('DISTRO_FEATURES', 'x11', 'x11', '', d)}"
   PACKAGECONFIG[x11] = "--enable-x --enable-xvideo,--disable-x --disable-xvideo,virtual/libx11 libxv libsm libice"

How can the depencency on virtual/libx11 still be there if DISTRO_FEATURES does not contain x11?
