There's a few ways to do this.  The first is to just put D_P = -1 on the 
new version and let distros opt to upgrade everything at once.  The 
second is to play virtual games like we do for libusb.  The first option 
is easier to implement than the second and depending on how wide spread 
the usage is might be the best route.
