#56606: port -D install doesn't work for subports

 I've clone macports-ports and point port to it with -D (i.e. port -D
 ~/macports-ports), the install command recognizes the changes on the top
 level port but not any subports, this makes testing subports difficult.

 Also, how come none of the subports functionality is documented?
