Hi!

Glad you're trying out VMKit!

As to your issue, there are two solutions:

The simplest is to disable classpath's need for X, by telling it to
not build its gtk peer (--disable-gtk-peer).  This will prevent you
from running most applications that provide a GUI however.  Depending
on your use case this might be acceptable.

Otherwise, ensure you have X11 installed (I'm not enough of a Mac user
to tell you the best way to do this, including any possible gtk
dependencies) and try the configure again.  Then take a look in
config.log to see why the check is failing and point it to the right
headers/libraries.  I'm happy to help with any further issues, but
might be somewhat unavailable over the Thanksgiving holiday.

Let us know how this goes for you, and sorry I can't provide any more
mac-specific help.
