thanks. i had to modify configure.am to not compile GLX, but then it
compiled through.
Unfortunately it doesn't really work.

Got 5 EGL configs:

 2:  Red Size = 8  Depth Size = 16
 3:  Red Size = 8  Depth Size = 32
 4:  Red Size = 8  Depth Size = 24
 5:  Red Size = 8  Depth Size = 24

zsh: segmentation fault  

How do i even set the fb device?
I don't think fbdev is what i want anyway, since i want _hardware_
opengl acceleration. Unfortunately it seems egl hides alot behind the
scenes, including dri. When i try to use egl_dri with an already opened
dri device, it fails. probably because dri cant be opened twice, but i
can't see  how to feed mesa with an open fd, and with already allocated
dri vbuffers, etc. Should i use the gallium drivers directly rather then
through egl?
