Hello all,

Short solution: install cygwin-provided wget and change CPAN setting to 
use /usr/bin/wget, not Windows native wget.exe.

To recap:

Long:

Another thread at http://www.cygwin.com/ml/cygwin/2005-02/msg00756.html speaks 
about trying other protocols (in case proxy/firewall screws up things in 
between) and ensuring that mounts are in binmode (type 'mount' to see things 
like  c:\cygwin\home\username\.cpan on /home/username/.cpan type system 
(binmode) ). 

After I checked these things, reinstalled gzip/zlib and wondered why even 
WinRAR can't see proper files, I thought that the download application (wget) 
is screwed. I checked the cpan.PM but changes to wget options would not help. 
So only then it dawned on me that the _native Windows_ wget.exe (GNU Wget 
1.9.1) which I had in c:\windows\system32 does not work with Cygwin. It just 
doesn't do the right thing with Cygwin when doing -O - (to output downloaded 
file to stdout). So, solution: run Cygwin setup and install cygwin-provided 
wget. Then 'perl -MCPAN -e shell', o conf defaults, o conf init and give it new 
path to wget (/usr/bin/wget).


Cheers.
