The ebuild depends on >=x11-libs/libdrm-2.4.5, but this should be 2.4.6 as indicated by the configure step below: (...) checking for PCIACCESS... yes configure: X server has new mode code checking whether xf86RotateFreeShadow is declared... yes checking for DRM... configure: error: Package requirements (libdrm >= 2.4.6) were not met: Requested 'libdrm >= 2.4.6' but version of libdrm is 2.4.5 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables DRM_CFLAGS and DRM_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. (...) I do appreciate the developers' work, but if I may be a little bit critical: I don't understand that people just copy ebuilds blindly and submit them if they work on their system, which is probably bleeding-edge wrt a lot of other packages as well. Re-checking dependencies should always be done. Reproducible: Always
Fixed directly in portage. Thanks
