   I see from a google search that MacPorts lacks logging. Would it be that difficult to add
a very simple logging facility (instead of the complex proposal from https://trac.macports.org/ticket/2020)?
Just have port add a line to a /opt/local/var/port.log file on successful completion of a task.
Having a log modelled on yum.log which shows a time stamp, port action and port name would 
allow for confirmation of misbehaviors by port when dealing with dependencies. Especially since
often these problems will only be found after the fact when the Terminal window from the port
session will have been closed.
