One option would be to simply hold back any message until all ports 
installed and output them afterwards. So all messages would be at the 
end of the log.

Or, use some new target like print_message {}, but which would need to 
be stored in the registry after installation to be always available in 
the state as it was on install.

For this rather long nedi help, I would prefer to put them into some 
file like /opt/local/share/doc/nedi/INSTALL.macports and just print a 
message that there is additional help in this file.
