Description Juan Simón 2015-12-01 10:25:39 UTC 
I have upgrade Gentoo today (I'm doing a new installation). 
When Gentoo tries to update x11-proto/glproto from 1.4.17 (yesterday) to 1.4.17-r1 (today) it fails due to file collision:

 * package x11-proto/glproto-1.4.17-r1 NOT merged
 * Detected file collision(s):
 * 	/usr/include/GL/glxproto.h
 * 	/usr/include/GL/glxtokens.h
 * 	/usr/include/GL/glxmd.h

Those files were installed by previous version in another path:

# portageq owners / glxmd.h glxproto.h glxtokens.h
x11-proto/glproto-1.4.17
	/usr/lib64/opengl/xorg-x11/include/GL/glxmd.h
	/usr/lib64/opengl/xorg-x11/include/GL/glxproto.h
	/usr/lib64/opengl/xorg-x11/include/GL/glxtokens.h

Why doesn't it delete that files?

Reproducible: Always
Comment 1 Juan Simón 2015-12-01 10:32:54 UTC 
I have solved it changing "FEATURES=-collision-protect" in make.conf before update this package.
Comment 2 Juan Simón 2015-12-01 10:35:55 UTC 
In any case, FEATURE="collision-protect" shouldn't have failed in this case because they are files of the same package.
Comment 3 Juan Simón 2015-12-01 11:11:46 UTC 
Same problem upgrading media-libs/mesa from 10.3.7-r1 to 11.0.6.
Comment 4 Chí-Thanh Christopher Nguyễn gentoo-dev 2015-12-07 11:29:52 UTC 
These are files which were previously managed by eselect-opengl.

FEATURE="collision-protect" is not enabled by default for good reason, and if you set it (because you are concerned that portage might overwrite your files) you have to handle the fallout.
