USE="xcb" emerge cairo Actual Results: configure fails with: checking for cairo's XCB backend... checking for xcb... no no checking whether cairo's XCB backend could be enabled... no (requires XCB http:/ /xcb.freedesktop.org) configure: error: requested XCB backend could not be enabled Expected Results: normal build process emerging xcb-utils fixed it even though other xcb* packages were present.
