I would say if you're going to be modifying a plist, you should be using a tool designed to do so, like "defaults" or "PlistBuddy". Not sure if we have any Tcl functions or wrappers around those utilities in MacPorts already, but having a wrapper around PlistBuddy especially would be nice of us to do, since PlistBuddy is sometimes hard to find. It's installed in /usr/libexec as of Snow Leopard, but before that, you have to go hunting through various OS X installer receipts to find a copy. Many Apple Installer packages use PlistBuddy, and have code that does that locating. Here's some other code that does that:
