The URI module must be installed.  WWW without URIs would not
be that great :-)

The HTML::Parser is needed to extract correct <BASE> information from
HTML so that we can resolv relative links correctly.

The Base64 encoding is used in authentication headers in HTTP.

    print <<EOT;
$@
The libwww-perl library normally use the Net::FTP module when
accessing ftp servers.  You would have to install this package or
configure your application to use a proxy server for making ftp
requests work.  Net::FTP is part of the 'libnet' distribution.

    print " failed\n";
    $missing_modules++;
    print <<EOT;
$@
The Digest::MD5 library is needed if you want to be able use the
experimental "Digest Access Authentication" scheme.  Since very few
servers implement this authentication scheme, you should normally not
worry too much about this.
