For developers there has to be a starting point -- that is, what does a
developer wanting to port gnuchess install?

Well, the solution proposed here sounds like a very good approach to
me.  It allows for having a stable user-space very early on, so that
people _can_ install it on their athlon64's and start porting all the
other applications.
