I found the problem, for this case at least. It's an incompatibility 
with the version of CGI.pm. Later versions of CGI.pm require something 
like this:

--- W3C/Util/W3CDebugCGI.pm     8 Sep 2003 19:26:44 -0000       1.83.2.1
+++ W3C/Util/W3CDebugCGI.pm     6 Jul 2008 19:46:53 -0000

      my $putData = undef;
      if ($ENV{'REQUEST_METHOD'} eq 'PUT') {
         if (my $contentLength = $ENV{'CONTENT_LENGTH'}) {
-           &CGI::read_from_client(undef, \*STDIN, \$putData, 
$contentLength, 0);
+           &CGI::read_from_client(undef, \$putData, $contentLength, 0);
             $ENV{'REQUEST_METHOD'} = 'GET';
         }
      }

in addition to the patch in my message
