Maybe it's not really important... The ebuild depends on xorg-server-1.5 and libdrm--2.4.5 but xf86-video-intel-2.7.0 need libdrm-2.4.9 and xserver-1.6.1 (see : http://intellinuxgraphics.org/2009Q1.html) Reproducible: Always
Oh, I forgot to remove 2.7.0 from the overlay when I moved it to portage. And for the record, the one in portage has the correct libdrm dependency. Thanks
