Just for the future, Portfile development is usually discussed on
macports-dev, where you would reach more developers. The discussion on
macports-users is about usage of the port command and problems with
installs and upgrades.

A few ports use this approach, citing from the mongodb port:

  startupitem.executable  sudo -u ${mongouser} ${prefix}/bin/mongod ...

While this adds an additional processes to the hierarchy, I do not see
any problem with that. The su/sudo keeps running until the command exits
and any signals sent to su/sudo will be relayed to the executed process.
