This sounds like a configuration issue.

Firstly, the machine config needs to make sure the libgles-omap package
is included in the image, probably through something like the XSERVER
variable although I appreciate we don't have anything for egl at this
point.

Secondly, the libglex-omap module should CONFLICT/REPLACE/PROVIDE the
bits of mesa it replaces.
