You're not supposed to do a make install on top of another install. 
You're supposed to first do a make uninstall in the old tree than a make 
install in the new tree.

Semantically, this is how a distro package upgrade works.

Once we're no longer generating an executable, we should be removing it 
from the system.

It's up to the user to remove old files from the system.
