Is this accessible online someplace?

You will like it.  Your friend will like his G5 even more, it seems.

Ack!  you're right, and I had meant to post something about that months 
ago when I (re)discovered that.  I originally came across that problem 
way back in 1996, when I first installed & compiled Radiance on an old 
PII/266.  I thought - get this - that something went wrong during the 
compile, and that was why vi was loading instead of rview, that somehow 
the compile process grabbed bits of vi's source when compiling Radiance. 
  What the hell did (do) I know?  It was but one of many false starts in 
my Radiance explorations.

It's got nothing to do with the shell, the problem is that if you blow 
off the default location and install the Radiance binaries someplace 
other than /usr/local/bin, even if you place your new location on the 
RAYPATH & PATH, it's likely to be lower in priority than the location of 
the symbolic link to vim that seems to be present on a LOT of the 
current Linux distros.

Kudos for pointing that out to the list, Jeffrey.  I guess most people 
just accept the default location for the Radiance binaries so they never 
see this problem.  Do a "locate rview" on your systems though; lots of 
you will probably see a link in /bin, linking rview to vi...

Greg, maybe a little warning could be added to the install script?
