As a rule, you should not use sudo unless you're pretty sure that you
know why you need it. The operating system already has a solution for
keeping one user's processes from scribbling over files owned by another
user. Try to take advantage of it.

(Admittedly, accidents do happen. Ryan just brought up a not-uncommon
circumstance: Sometimes third-party developers use MacPorts to create
installers for distribution, but they don't use a custom prefix, so the
installers scribble into /opt/local — usually after asking you for admin
authentication.)
