Thanks for the clarification with regards to how the XS Scalar::Util failed to
load.  

Ordinarily not being able to load an XS shared object would be a fatal error,
which Apple would hopefully have caught.  However, in the case of
Scalar::Util, failing to load the XS shared object triggers a fallback to the
Pure-perl implementation -- which is incomplete.  IMO, that's poor API design
-- a nasty little trap which you can guarantee some fraction of your users are
going to fall into.

Dunno what's up with my system, but right now I'm running 10.5.7 and I get the
"weaken" failures when I use the stock Perl.

Whatever.  For my laptop, I think I'm going to continue to use the manually
compiled Perl.  For the Mini, though, I'm messing with the system Perl.

"./Build distclean" wipes out the "Build" script and the "_build" directory.
On dev branch KS, I don't think there will be a difference.  For stable branch
KS, the code autogeneration work is done by Build.PL rather than Build,
though... and I just got in the habit of running "distclean" rather than
"clean" from back then.
