It's easy.  You just run autoconf without any parameters:

  mv configure SAVE-configure
  /berman/migchain/install/host/autoconf-000227/bin/autoconf
  diff SAVE-configure configure

You could mess with your $PATH, but I find it easier to just type
in the long path name (using a lot of TAB autocompletion the first
time, and "!/" after that).

My autoconf skills are only a little bit higher than yours, so if
Nathanael or Daniel comes in and tells you to do it different,
that's fine.
