Many thanks for the reply. The question you answered is not the one I wanted answered. What I have done so far has shown that upgrading all wanted ports with a single invocation of 'sudo ./restore_ports.tcl myports.txt' does not work for me because of errors. I want to upgrade a single port or at most a handful with each invocation of ‘sudo port install …’ and for that I need to know the dependencies for each port that I want.

Thanks again for trying to help; I’m sorry that the description of what I wanted was inadequate.

Barrie.
