..without counting the time needed to convince the reworked build
system to work on the many machines for which the current one
works (or at least, sort of works) ...

Anyway: I am not completely happy either with the current
build system. In additional to occasional glitches like this one:

on CRAYXT5, after taking out pw2casino part I get the following
compilation error in 'dist.x'

there is a more general problem: circular dependencies between
Modules/, PW/, CP/, flib/. One of these days we need to re-order
things and make such dependencies disappear. I hope that once
this is done, it will be much easier and safer to work on the
installation mechanism.
