Be forwarned - the Makefile has changed, so you need to re-run
autogen.sh.  If you do not, then you may be missing a symbol.

If you are missing a symbol, then X will crash, and if you are using
VGA, then you won't be able to get back your screen.  Either run X
from a remote or serial terminal or use a framebuffer to avoid this
annoying behavior.
