That's because you should *never* run delete-old or delete-old-libs from
a source tree that is newer than your installed system.  It may delete
files which have been obsoleted by changes you haven't yet built and
installed, to the point where you may be unable to build and install
those changes.  In this particular case, it will, at the very least,
break ssh and svn / svnlite.
