Depends on your definition of optimal ;-) The ideal, from BBv2's point 
of view, is to have a different type of shared target for a bundle. With 
a different type other options can be adjusted without impacting the 
regular shared lib building. And if I remember correctly, just using 
-bundle isn't enough to build bundles.

This would be the wrong way to go about doing this. We intentionally put 
the short name so as to allow easier standalone deployment of libs as 
it's what people using Unix are familiar with. Usually it's up to the 
installer, whether it's the user or an install script, to run the 
library renaming program to re-tag the library with the installed path. 
I don't remember the name of the Xcode tool for doing this at the moment 
though.
