CPAN failure in 5.16.1 (+ solution)

It seems there have been no postings to the list for over a year, but 
here goes anyway.

Last night I installed Perl 5.16.1 in /usr/local/ and immediately 
encountered problems when I tried to install and update modules using 
CPAN.  The error is copied below.  I could see no solution to the 
problem and was expecting a very tiresome late night, until by some 
stroke of luck I thought of trying cpanplus to install the modules 
and to install CPAN itself.

You can imagine my relief when this worked, and now CPAN runs without a hitch.
