Then I checked permissions in the directory. Files updated by the sync do not have these permissions. For example, the gegl and glfw Portfiles have 644 permissions instead of 770, so only the macports user can write to them, so trying to edit them in my editor results in the administrator password prompt that I'm trying to avoid.

why not just update your sudoers permissions file, to allow your main 
account to run the port command as root, without requiring a password 
(or just give it a longer timeout, which would be my preferred way) ? 
Seems easier than faffing with file permissions ..
