Yep, chmod on the build, distfile and package directories is how I am
running macports. Then port archive works for most ports, but it stops
anytime it enters the install phase of a dependency, requiring me to
sudo install then retry. Some ports however require root privileges for
destroot either because they want to create a user or they try to chown
some files or put setuid bits, those kind of things.

Then maybe port selfupdate does not require root (I have also chmodded
the source directory to be able to port sync without being root, but
each sudo port selfupdate, steals some rights...), which is a concern as
my first goal was to avoid fetching and extracting as root.

Then 'man portfile' is here: it's clearly official, it is up-to-date
enough, it contains examples for better understanding, you must read it.
For what goes where, there is 'man porthier' (not as up-to-date, but
however informative). You can also read 'man portstyle', it is short and
largely not applied (indentation rules for example) but contains
And the "exampleport"
Good reading, I hope you will write beautiful portfiles :)
