In playing a little with deleting libEGL it appears to demolish much
of the GUI infrastructure, deleting something like 4G of applications
and libraries. At that declaration I hesitated, and hit n. 8-)

If it's really the only way to update the system please indicate so,
and I'll give it a try. I'm on RPI2, running -current.

Thanks very much,
