How to get portinstall to 'shut up' so I can run it in background

[Clint Olsen]

I've tried redirecting standard output/error, both /bin/sh and /bin/csh,
and I can't run this in batch.  I'm trying to build gnome which takes
hours, and I want it backgrounded so that if this SSH shell disconnects it
doesn't crater the build.  You would think that --batch would make this
happen, but no go.

Thanks,
