That's only going to help so much.  Most ports are going to generate compiler
warnings that go to stderr, which will still spam your screen.

First off, I recommend directing to a file instead of /dev/null.  That way
if it fails, you have the output to review.  Secondly, redirect both
standard out and standard error.  In bourne shells:

make install clean >~/buildlog.txt 2>&1 &
