This is a problem accute only because SVN does not have the

We may version the modification time of the generated files, but that
is not a solution I like.

Yes, if and when we need to regenerate noweb source files, it is a bug.

That is a reasonable requiremnt for developers. I'm not sure it
exports to most end users without getting the entry bar too high.
This is an issue I'm ambivalent about and don't have a clear cut
answer for.
Let see, what the requirements would be:
(1) need an installed lisp -- I still believe me must have GCL
around as long as we cannot build Axiom with other systems.
(2) need an installed noweb -- noweb is not as widely packaged
as Lisp systems.
(3) needs socket support -- I believe this is a bogus requirement
at least for the time being.
(4) needs installed latex
