    Also the eventual plan is that each external package will get  
installed directly
to the prefix location (instead of being installed first in the petsc  
location and
then copied over to the prefix location).

    This is a little funky to think config/configure.py is doing an  
install; but it
is doing the install of the external packages you requested.
