This is the SRC_URI from the eclass. SRC_URI="${XORG_BASE_INDIVIDUAL_URI}/${XORG_MODULE}${P}.tar.${XORG_TARBALL_SUFFIX}" This is not correct at least for media-fonts/font-util, this needs to be adjusted to: ${XORG_BASE_INDIVIDUAL_URI}/font/${XORG_MODULE}${P}.tar.${XORG_TARBALL_SUFFIX} I haven't looked for the other packages that use xorg-3.eclass
sorry, my bad. stale xorg-3.eclass was the culprit.
