macports without root?

[Paul M. Lambert]

I'm trying to build a macports installation that runs entirely out of  
a user's home directory.

I've compiled macports without launchd support, and set the install  
user and group to the appropriate user.

However, when I try to run "port install mysql5" it fails, apparently  
because it's trying to chown a file to root.

Is this a problem with that port, or does macports require root in  
general?

If it's the latter, any suggestions on how I could go about patching  
it to allow fully non-root user installations?
