As a data point I run "port -u uninstall" every Sunday to clean out old 
(i.e. saved) ports, then "port selfupdate" every Monday and follow my nose 
from there.  There is no specific reason for that timing; it's just how 
the care and feeding of MacPorts through osmosis worked out over time...

As an aside, my own MacPorts is semi-trashed due to Migration Assistant 
refusing to bring MacPorts from the old MacBook to a newer Pro, so I 
stupidly(?) decided to do it by hand instead of starting from scratch; as 
a result I'm now hung up on finding a suitable Xcode for the Pro with 
Sierra 10.12.6 and seeing all sorts of conflicting advice.

Hint: don't believe the answers on StackOverflow; its mission in life 
appears to be to mislead newbies...
