Comment (by davide.liessi@…):

 Maybe I'm making it too simple, but why don't you test for existence of
 pythonXY-config and call it only if it exists?

 That way, when only processing the Portfile to make PortIndex, retrieve
 information or check dependencies, `abiflag` would sometimes have the
 wrong value, but the Portfile would execute without errors.

 If I understand correctly, `abiflag` needs to be set to the correct value
 only when actually installing/upgrading the port, and at that point Python
 would have already been installed and pythonXY-config would exist.
