I suspect you are correct in your diagnosis! I continued on after I
posted and hit the site with the traditional 'update cygwin' hammer
and while cpan HTML::Strip still failed, I was able to move to
.cpan/build/HTML-Strip... and finish the install by hand. I believe
the remains of the previous failed attempts left behind enough cruft
to block the usual methodology. Happy with the results, client is
happy as well and the damn machine is updated despite a prevailing
attitude of 'if it is not broken, don't fix it...'
