Still no joy in Mudville, I'm afraid.

It still tries to go online for authors/01mailrc.txt.gz. If I say "no", it continues with:

CPAN: YAML::XS loaded ok (v0.26)
Alert: While trying to 'parse' YAML file
 'C:\Perl64\cpan\FTPstats.yml'
with 'YAML::XS' the following error was encountered:
  Usage: YAML::XS::LibYAML::Load(yaml_str) at C:\Perl64\lib/YAML/XS.pm
+ line 70.

That's trying to install the later ExtUtils::MakeMaker.
