Thank you for the information.

I've been experimenting with different configure options when building
the MzScheme source code distribution for OS X. To get a normal UNIX-
style build on OS X it seems sufficient to do

./configure --enable-xonx --prefix=/usr/local

Also it seems that the --enable-xonx option does not have much effect
on the MzScheme build. Is it true that there is not really any Quartz
or X11 components in the MzScheme source code?
