Make install or upgrade for new install location

[Larry Stone]

I have been running Postfix under Mac OS X for a number of years (now on 
OS X 10.7.latest (Lion)). I am working on moving away from the Apple 
provided and customized Postfix to "real" Postfix built from sources. I've 
successfully built Postfix but not yet tested. To avoid having it 
overwritten by Apple updates to Postfix, I'm planning to install in 
/usr/local/ (e.g. /usr/local/etc/postfix, /usr/local/sbin, and 
/usr/local/libexec/postfix).

When it comes time to install, do I do "make install" or "make upgrade"? 
It's not clear to me if "make upgrade" will work when the upgrade is in a 
different location than the previous version.
