Portupgrade has a no-execute option (-n) which will allow you
to see what would be done without actually performing the
operation; for example:

	portupgrade -nfRr gd

will end with a list of ports that would be updated.  Another
port you may find useful is ports-mgmt/pkg_tree which will
show a dependency tree for a port.

HTH,
