Nicolas, thank you very much for your advice and for being so generous with
your time.  Your suggestions have helped a lot.  I was not aware that one
could compress the binaries and just copy them from machine to machine.  I
am still studying your example and it will take me a little time to try
your suggestions since I don't have access to my lab at the moment.  Still,
in the meantime I did try out remotely logging in as root using "ssh
root@<other machine IP>.  so, if I can log onto each machine then I should
be able to change the PATH variables and then move and uncompress the tar
files.  I suppose that in theory I could write a script to do this
automatically but by the time I get that working I could have probably just
gone from machine to machine with a CD of the tar files.  Anyway, I will
write back when I try this out. Thanks again, Chris
