I think this problem is due to upgrading our Mac build machine to 10.6.
The main executable is built in a 10.5- an 10.4-compatible way, but the
plot library isn't.

We'll fix that. Meanwhile, if you have the Apple developer tools
installed, you can probably work around the problem by deleting the
"/Applications/Racket v5.0.1/collects/plot/compiled/" directory and
running 

  "/Applications/Racket v5.0.1/bin/raco" setup plot

in a terminal to rebuild the library.
