curl -v 'http://search.cpan.org/meta/IO-Tee-0.64/META.yml'  shows HTTP 200 and Content-Length: 0 bytes.

I think a possible solution here is having a variation of http called http_withheaders, because many backends such as LWP, curl , HTTP::Tiny, have mechanisms to provide headers,

curl -D $file # tells curl to dump headers to this file

wget has --save-headers ( which prepends the resulting headers to the OUTPUT file )

And being able to return headers, and as a result, know whether a URI is a 404 or an empty file, will help solve this bug, and as a result, also solve https://github.com/miyagawa/cpanminus/pull/183
