  Basically, yes, but you don't have to do that by hand.  If you have an
up-to-date pkgsrc tree, you can use the 'make update' target to update
your installation, even from pre-compiled binary packages.  To do that,
set 'UPDATE_TARGET=bin-install' in /etc/mk.conf, then do a 'make update'
on the package you want to update (e.g., gnome).  For more information,
see the descriptions of the 'bin-install' and the 'update' targets in
the package documentation.
