CPAN.pm doesn't recognise when curl fails to find a file. Transcript of my
CPAN session is:
$ /home/nick/Sandpit/snap5.9.x-26999/bin/perl5.9.3 -MCPAN -eshell
Terminal does not support AddHistory.
cpan shell -- CPAN exploration and modules installation (v1.8359)
ReadLine support available (try 'install Bundle::CPAN')

Warning: No checksum for YAML-0.55.tar.gz in /home/nick/.cpan/sources/authors/id/I/IN/INGY/CHECKSUMS.
The cause for this may be that the file is very new and the checksum
has not yet been calculated, but it may also be that something is
going awry right now.
Proceed? [yes] yes
Scanning cache /home/nick/.cpan/build for sizes

What's happening is:
$ /usr/local/bin/curl -L http://www.perl.org/CPAN/authors/id/I/IN/INGY/Test-Base-0.48.tar.gz
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML><HEAD>
<TITLE>404 Not Found</TITLE>
</HEAD><BODY>
<H1>Not Found</H1>
The requested URL /authors/id/I/IN/INGY/Test-Base-0.48.tar.gz was not found on this server.<P>
</BODY></HTML>
$ zcat /home/nick/.cpan/sources/authors/id/I/IN/INGY/YAML-0.55.tar.gz
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML><HEAD>
<TITLE>404 Not Found</TITLE>
</HEAD><BODY>
<H1>Not Found</H1>
The requested URL /authors/id/I/IN/INGY/YAML-0.55.tar.gz was not found on this server.<P>
</BODY></HTML>
So somehow the curl 404 output is getting compressed and written to
~/.cpan/sources/authors/id/I/IN/INGY/YAML-0.55.tar.gz
and assumed to be a successfully downloaded tarball.
This is CPAN.pm 1.83_59, in bleadperl. (Freshly installed at patchlevel 26999;
I answered "no" to "are you ready for manual configuration?")
