Is this specific to the eselect module and not the 2.x series?  Do you
have the eselect-opengl-1.0.1?  There was a bug in 1.0.0 that looks like
what you describe, and I fixed it in 1.0.1 before removing it from
package.mask... but I did the commits about the same time, so I suppose
there could've been a concurrency issue...

they should be located in /usr/lib/opengl/xorg-x11/include

Please verify that you have eselect-opengl-1.0.1.
