libxcb RDEPENDs on xcb-proto - however, xcb-proto is apparently only used during libxcb's build for generating header files in /usr/include/xcb. xcb-proto RDEPENDs on python, which causes an effective python dependency for libxcb. I suggest moving xcb-proto dependency to DEPEND in the ebuild. If that is the wrong thing to do for some reason, I suggest the following approach: 1. Split xcb-proto's xcbgen package into IUSE=python. 2. If libxcb needs xcbgen during build (no idea whether it does), then RDEPEND on xcb-proto, and DEPEND on xcb-proto[python] 3. If libxcb doesn't need xcbgen during build, then no change is needed in libxcb's ebuild.
The problem is probably similar to bug 342393. While libxcb does not strictly runtime-depend on xcb-proto, packages that build against libxcb might fail if xcb-proto is not installed.
I have temporarily put xcb-proto in package.provided, unmerged it, and rebuilt the libxcb-dependant packages that I have: [ebuild R ] x11-libs/libX11-1.4.4 USE="-doc -ipv6 -static-libs -test" 0 kB [ebuild R ] x11-libs/xcb-util-0.3.8 USE="-doc -static-libs -test" 0 kB [ebuild R ] x11-drivers/xf86-video-intel-2.17.0-r3 USE="dri sna" 0 kB [ebuild R ] x11-apps/xdpyinfo-1.3.0 USE="xinerama -dga -dmx" 0 kB [ebuild R ] x11-apps/xlsclients-1.1.2 0 kB [ebuild R ] x11-apps/xwininfo-1.1.2 0 kB [ebuild R ] x11-libs/startup-notification-0.12 USE="-static-libs" 0 kB All merged fine. Maybe xcb-proto can be move to DEPEND after all.
/usr/lib/pkgconfig/xcb-ewmh.pc:Requires: xcb xcb-proto Not sure if any package in tree builds against that.

Doesn't seem so: # find /usr/portage -name '*.ebuild' | xargs grep -l xcb-util-wm /usr/portage/x11-libs/xcb-util/xcb-util-0.3.8.ebuild /usr/portage/x11-libs/xcb-util-wm/xcb-util-wm-0.3.8.ebuild
Hi, any news? Can xcb-proto be moved to DEPEND?
(In reply to comment #5) > Hi, any news? Can xcb-proto be moved to DEPEND? No. Not really. Portage needs to support a new kind of DEPEND for this case.
After looking at the pkgconfig files, it appears mostly safe to drop the RDEPEND on xcb-proto. The only package that needs to be adjusted appears to be xcb-util-wm, which should have the xcb-proto dependency anyway as xcb-ewmh.pc requires xcb-proto.
Can I proceed with this as QA? I'm hitting this on one of my projects.

The dependency on xcb-proto was changed to build-time only. Regarding the xcb-util-wm, the pkconfig entry seems bogus at first glance, but that is something upstream will have to address.
This change broke cross compiling, bug 412909.
