 When a port with dependents is deleted from MacPorts, the system
 often ends up in the following kind of inconsistent state:

 {{{
 $ port list xorg-liblbxutil
 $
 }}}

 So it's not in MacPorts now.

 {{{
 $ port echo installed | grep xorg-liblb
 xorg-liblbxutil                @1.0.1_1
 }}}

 But it's still installed.  Let's uninstall it:

 {{{
 $ sudo port uninstall xorg-liblbxutil
 --->  Unable to uninstall xorg-liblbxutil 1.0.1_1, the following ports
 depend on it:
 --->    xorg-libs
 Error: port uninstall failed: Please uninstall the ports that depend on
 xorg-liblbxutil first.
 }}}

 We can't uninstall it, because of a dependency.
 But wait - xorg-libs depends on a port that is not in MacPorts?

 {{{
 $ port deps xorg-lib | grep xorg-liblbxutil
 $
 }}}

 Or does it? MacPorts seems very confused.
