Point me at a 'curl' or 'wget' retrievable tar ball and I'll build it
for ya.   :-)

I think the problem is that the distributors are put off by the CPL
(AT&T's GPL wannabe).

Meanwhile, this reminds me of a story ... feared it might be urban
legend, but it checks out.  Microsoft appears to have taken some of
their Unix-workalike parts via MKS (which itself is an excellent piece
of work).  So once upon a time this certain M$ project manager was
rattling on about how they were going to include a version of the Korn
Shell in an upcoming release (probably SFU, which I have never gotten
to work anyway).  Someone in the audience questioned why M$ was so
back-leveled, why they did not have a more current implementation of
KSH.  The M$ PM said it was "pretty compatible" and things should be
fine.  This went back and forth until someone else in the audience
pointed out to the M$ PM that the questioner was in fact David Korn
