upgrade outdated example

[Tom Allison]

sudo port -u upgrade outdated
Password:
--->  Activating apr 1.2.12_1
Error: Activating apr 1.2.12_1 failed: Image error: Another version of 
this port (apr @1.2.11_0) is already active.

This is the kind up upgrade problems I run into.
I manually deactivate/activate the packages?
