 I have two versions of glib2 installed -- one universal (active), one non-
 universal (inactive). When I upgrade a port that depends on glib2 (in this
 case graphviz-devel) port first deactivates glib2 then reactivates the
 exact same glib2. It shouldn't do that.

 This is with MacPorts trunk @38333 on Mac OS X 10.4.11 Intel with Xcode
 2.5.

 {{{
 $ port installed glib2
 The following ports are currently installed:
   glib2 @2.16.5_0
   glib2 @2.16.5_0+universal (active)
 $ port upgrade graphviz-devel
 --->  Deactivating glib2 @2.16.5_0+universal
 --->  Activating glib2 @2.16.5_0+universal
 --->  Fetching graphviz-devel
 [snip]
