Dangling symlink kernel-tree/scripts/tree.py breaks the CML2 install,
rm kernel-tree/scripts/tree.py first.

There are still discrepancies between the output produced by different
forms of make *config.  I am also seeing spurious deduction messages
which may be related or may be a separate problem.

Examining your build environment...
Good. You have Python 2.x installed as 'python2.1' already.
Python looks sane...
Good, your python has curses support linked in.
Good, your python has Tk support linked in.

Why are those deduction messages appearing in menuconfig?  I just did
make oldconfig, the config should be stable.  I did not change anything
in menuconfig, just saved it.

OUCH!  The output from make menuconfig has significantly more options
than make oldconfig when given exactly the same input.  I thought one
of the selling points for CML2 was different front ends but with
identical back end processing.  I don't like the way that the resulting
config varies when fed to different front ends.
