I run MacPorts as root to ensure smooth installation, but I expect the bulk of the work could easily occur without root permissions, and without having anything to do with the kernel. Is this something I can change or a problem with MacPorts?

Please give the actual number from 'port version'; from our point of
view it's difficult to know whether a user actually has the latest
version or just thinks they do. :-)
How much RAM do you have, and what are your buildmakejobs and
