You can download these roots and place them into Roots/ 
opendarwin.org/.  Then, when darwinbuild copies files into the  
BuildRoot, these will be used.

You can clean out the entire BuildRoot directory.  Otherwise, there's  
not much need to do a 'make clean' since the build number gets  
incremented each time, so you'll start with a fresh OBJROOT, SYMROOT,  
and DSTROOT with each build.
