Updating a program

[Jack Raats]

Hi,

I have the following problem. I¹ve installed dovecot using pkg install
dovecot.
After installing I used svn to update the /usr/src and /usr/ports.
Portmaster ­a does not update dovecot which I installed using pkg.
How can I update dovecot?
(I¹m mentioning dovecot but in fact there are more programs I have to
update)

Thanks
Greetings
