Hi Blair,
I've committed new mesa packages to pkgsrc-wip (Mesa, MesaLib, glu, and glut). Unless I forgot to commit something (possible), everything up to glu (at least with dri support) should build on NetBSD (at least 4.0+, I'm using i386 on current).
It's okay for me, at least Mesa: > pkg_info | grep Mesa MesaLib-7.0.3rc2 Graphics library similar to SGI's OpenGLglxinfo still reports no DRI, but I get over 1200 fps with glxgears, so drm is fine.
I'll try to see what I can do to help you at the end of the week or at the beginning of next one.
Thanks for commiting. VincentPS : xlockmore OpenGL modes are broken since 7.0.0. Do you have the same behavior?
