This happens 100% on systems which supports IPv6 but has not a bound IPv6 
address except localhost (::1) and on systems without any IPv6 support.
This was not verfied on a system with fully configured IPv6.
If IO::Socket::INET6 is installed but IO::Socket::IP is not - even the 
make tests are failing and the module is no longer working anymore.
If IO::Socket::INET6 is uninstalled, the module is working fine in any 
case.

This is related to the changes 6.06 -> 6.07

$VERSION = "6.07";
unless ($SOCKET_CLASS) {
    # Try several, in order of capability and preference
    if (eval { require IO::Socket::IP }) {
       $SOCKET_CLASS = "IO::Socket::IP";    # IPv4+IPv6
    } elsif (eval { require IO::Socket::INET6 }) {
       $SOCKET_CLASS = "IO::Socket::INET6"; # IPv4+IPv6
    } elsif (eval { require IO::Socket::INET }) {
       $SOCKET_CLASS = "IO::Socket::INET";  # IPv4 only
    } else {
       require IO::Socket;
       $SOCKET_CLASS = "IO::Socket::INET";
    }
} 


This is the dmake output from windows

It would be nice to have an option to preselect the $SOCKET_CLASS to use 
at module load time, at least before the call to Net::HTTP->new() or as an 
option in this call.
Now, setting $Net::HTTP::SOCKET_CLASS to any value before 'use Net::HTTP' 
or 'require Net::HTTP' is useless, changing it after 'use' or 'require' 
does not change @Net::HTTP::ISA - these variables are all not exported.
