force portupgrade to build port even with -P ?

[Palle Girgensohn]

Hi!

I use portupgrade an I love it. Thanks a lot!

A question: I usually do portupgrade -PR to upgrade stuff, and the packages 
are fetched from bento or som ftp server. But, for some packages, I have to 
use the port, because I have extra options set in MAKE_ARGS, like 'print/*' 
=> 'A4=yes -DA4 PAPERSIZE=a4' for example. If I update som port with -PR, 
and this port depends on ghostscript, for example, ghostscript will be 
installed from a package, naturally built without these MAKE_ARGS. My dream 
would be a setting in pkgtools.conf where I set something like 
`ALWAYS_USE_PORT' for certain ports that shall never use a package built 
off-site. Can this be done?

Thanks,
Palle
