You can get nmake for free from MS. ( A [id://Super Search] for 'nmake' would have found Link to download NMAKE from M$).

However, Mail::WebMail::Gmail is a pure perl module, so it can be installed manually. But just download nmake from the link above and put it somewhere in your path. Then try again.

So I managed to install the the Gmail componnent on my machine by installing another repository

http://trouchelle.com/ppm10/package.xml

I use the following for code

use strict;
use Crypt::SSLeay;
use HTTP::Cookies;
use HTTP::Headers;
use HTTP::Request::Common;
use LWP::UserAgent;
use Mail::Webmail::Gmail;

my ( $gmail ) = Mail::Webmail::Gmail->new(username => 'my_username', p
+assword => 'my_password' );

### Test Sending Message ####
my $msgid = $gmail->send_message( to => 'drblove@yahoo.com', subject =
+> time(), msgbody => 'Test' ); print "Msgid: $msgid\n";
if ( $msgid ) {
    if ( $gmail->error() ) {
        print $gmail->error_msg();
    } else {
        ### Create new label ###
        my $test_label = "tl_" . time();
        $gmail->edit_labels( label => $test_label, action => 'create' 
+);
        if ( $gmail->error() ) {
            print $gmail->error_msg();
        } else {
            ### Add this label to our new message ###
            $gmail->edit_labels( label => $test_label, action => 'add'
+, 'msgid' => $msgid );
            if ( $gmail->error() ) {
                print $gmail->error_msg();
            } else {
                print "Added label: $test_label to message $msgid\n";
            }
        }
    }
}

I get the following error:

Use of uninitialized value $host in concatenation (.) or string at C:/

I get the following error

The "error" you quoted is not an error at all. Those are simply warnings - the fact that $host, $page and $msgid are uninitialized is only a problem if they need to contain certain (initialized) values.

If that was the only warnings you got, and the message was sent, then all is well (at least as regards that particular exercise :-)
