[racket] mac plot crash

I think the problem is the way that the plot libraries are built.
They're created on a 10.6 machine. The build is supposed to use a flag
that creates 10.4-compatible binaries, but the flag is not propagated
to the plot build. I thought that the problem created to an
imcompatibility only with 10.4, but I guess it's worse than I thought.

If you can write to the Racket installation and you have the Apple
developer tools installed, you can fix the problem by deleting
"libfit.dylib" and "libplplot.dylib" and running `raco setup plot'.

Meanwhile, we've taken some steps to fix the problem for the next
version (after 5.0.2), though we're not there, yet.
