  this is another case of your space vs. time tradeoff.

  we use a set of sources for each architecture we have here.  i've 
  chosen one machine to house the "master" sources--it is here where
  patches and new software is added.  i then rdist the sources to
  the other machines that have the sources.  i use judicious use of
  the except_pat function in rdist so that .o, RCS, and other files 
  are not transported.  after rdisting the software to the other machines,
  i'll run a "make install" on those machines.  since rdist has only updated
  the new sources, only the new sources get recompiled.  
  
  after compilation, i make a "binary distribution" by rdisting the
  sources and libraries only from the source machines to other similar
  machines that don't NFS mount the source machine's /usr/new (in our
  case).

  actually, i could also make use of the rdist "special" command to 
  run the remote make install and binary distribution.

disclaimer: i can't mail out my Distfile because it doesn't exist yet. ;-)
i currently do this stuff with gnuemacs--X will be a simple extension.
