This is simply a deficiency in the way MacPorts currently works.  
MacPorts only knows that apr-util, subversion et al depend on apr. So  
when you try to uninstall (any version of) apr, it complains. Since  
you already have a newer version of apr installed, it's fine to  
uninstall the older one. You just have to force it to overcome  
MacPorts' objections.

sudo port -f uninstall apr @1.2.8_0
