sysinstall/ports?

[Bart Silverstrim]

Silly question but it's the first time I've played with X under 
FreeBSD...

I am in the process of installing X with Gnome from /stand/sysinstall.  
Will the packages added through this be the same as those from ports, 
or is there a way to use ports (portupgrade) to update the packages?

Do I have to do something to change the version used to the ports 
version if I want to keep up to date with portupgrade?

Thanks,
-Bart
