FreeBSD Port: portupgrade-20040529

[Roop Nanuwa]

Just a quick feature request for portupgrade/portinstall. It seems
that the -c/-C options are based on the whole set of installs so there
is no cleaning done inbetween dependency installations.

A problem occurs for some large meta-ports such as gnome2 or XFree86
which take quite a lot of disk space to build. I would suggest adding
an option that would allow a clean before and/or after each dependency
was installed as to minimize the maximum disk space used during
installation of such large ports.
