From the shell type (Don't include $:)
$: fetchmail -p POP3 -k -v -a --ssl -P 995 --smtpname xxx@xxx.xxx -u xxx@gmail.com pop.gmail.com

It will ask your password. Type your password and your emails will be forwarded to xxx@xxx.xxx address.

Parameter descriptions:
--ssl Gmail needs ssl connection to their mail server.
-P 996 Default pop3 port is 110. Gmail is using different port number and you have to define that port number. Remark: this is capital p.
-p POP3 Specify the protocol to use
-k Keep retrieved messages on the remote server mailserver.
-v Verbose mode. This writes the detailed output of the fetchmail to standard output.
-a Retreive both old and new messages from the mail server.
xxx@xxx.com Email address that emails will be forwarded
xxx@gmail.com Your gmail account.

Output should be like this:

Enter password for [xxx@gmail.com@pop.gmail.com]:
