Thanks, mostly.  It did try to install them, but the solver was/is
too smart, it comes up with 2 solutions 1/2 to uninstall 5.32,
install 5.30-x  and a bunch of other modules, and
(2/2) (Default) Don't uninstall 5.30 and keep 5.32.

I think the db-base in /etc/setup contains all the 5.32
compat modules -- so it basically saw all those uninstalls/reinstall
and just told me it was taking the easier path! ;-)

How does one pick a non-default choice at that point (not that
this was the only problem -- seems I have existing modules
installed in 5.32 under a local site_lib directory.
Problem there is that the existing modules there don't link:
HiRes.c: loadable library and perl binaries are mismatched (got 
handshake key 0x
800000770, needed 0x0)

But if i just push that dir out of the way, the 1st prog
I tried (pcalc that led to me trying cpan which didn't
work) now works, however the 2nd prog "dedup", wouldn't
work because of a missing prereq from CPAN which won't make:
>  dedup
Can't locate POSIX/RT/ in @INC (you may need to install the 
POSIX::RT::Semaphore module)
Tried making that, but I don't think it is compatible
with 5.32 due to incompatible changes in perl (vaguely remember
something like that, but not sure...)

But it fails with:

Trying to use the old 5.32 tree a fall back for anything
that fell to relying on /usr/local/lib/perl5/site_perl/5.32, I get the

mistmatched nonsense..(damn**)
HiRes.c: loadable library and perl binaries are mismatched (got 
handshake key 0x800000770, needed 0x0)

**-now perl libs are checking for version mismatches at dl-load time?
ARG! - it seems it used to work before this update, but is this
a new 5.32 update?  Got handshake key 0x800000770, needed 0x0? what
does that hex code mean? or what version was/is it looking for?

Sigh...where are the flags to 'setup' documented?

Last time I tried  setup.exe -h, it just hopped into the standard
download dialogues...

Thanks! ;^) (sigh)
