Some ports incorrectly show no dependents

[swebster@…]

This is for MacPorts version 1.9.0-rc2.

I set my requested ports and ran the command "port list leaves". This came up with a longer list than I expected. I investigated and it quickly became clear that something odd was up. The list contains many packages which are dependents of my requested ports. For example, automake is required by ImageMagick. However:

[/Users/swebster@swmb]$ port dependents automake
automake has no dependents.

and another example:

[/Users/swebster@swmb]$ port dependents gnome-common
gnome-common has no dependents.

but gnome-common is required by gimp.

[/Users/swebster@swmb]$ port list requested
gimp                           @2.6.7          graphics/gimp
git-core                       @1.7.1          devel/git-core
gri                            @2.12.18        science/gri
gwyddion                       @2.19           science/gwyddion
ImageMagick                    @6.6.2-0        graphics/ImageMagick
wine-devel                     @1.2-rc2        x11/wine-devel

The problem persists in the released 1.9.0, but I don't think I can update the description or version.

These are build-time dependencies and are thus not needed by the port after it is installed.
