I checked in a bunch of stuff yesterday that got a FreeBSD/AMD64
port kind of limping along.  Given a choice between (a) seeing
if those changes broke anything else and (b) sleeping, I chose (b).

I fixed at least enough to enable the Linux/AMD64 port to compile
itself without warnings or errors again, and checked those changes
into CVS a few minutes ago; I'll check the other ports in a few
minutes.

One of the changes from yesterday (the one that led to the error
below) introduced a new dependency between the image and lisp
kernel on Linux (and FreeBSD).  That really should have been
accompanied by some version number changes (to prevent an "old"
kernel from being used with a "new" image or vice versa) and
some new binaries.  Until that happens, the simplest way to
bootstrap these changes is to do:

shell> cvs update -d -P
shell> openmcl/openmcl64
? (rebuild-ccl :full t)
? (quit)

This dependency doesn't affect Darwin (though it's possible that
some other change made yesterday might inadvertently do so.)
