Yes, this is exactly the kind of thing that I wanted to avoid. So what 
we should do is:
1. run "make uninstall" in the old source tree and then remove that tree
2. download the new release and untar it thereby creating the new source 
tree
3. cd into the new source tree
4. run 'configure' with the appropriate arguments for your setup
5. run 'make'
6. run 'make install'
