The select_from_port shouldn't depend on the Run mechanism in general.
There should also be no problem with using it for noux packages. I
assume that there is something missing in your port description that
makes select_from_ports fail.

You can find a pretty comprehensive description of what is needed for
select_from_ports to work with a given port next to its implementation
in [1] (see also _lookup_port_hash_file in the same file).

Did this help you?
