Launching ocaml on Mac OS X results in a bus error

I just installed Ocaml on Mac OS X, and when I run ocaml I get a "Bus Error" with no other clue as to what might be happening. Can anyone offer suggestions on where to go from here?

EDIT:

I installed via package:

http://caml.inria.fr/pub/distrib/ocaml-3.10/ocaml-3.10.2-ppc.dmg

(I have an iBook G4, so PPC fits)

To start ocaml, I simply typed:

ocaml

      

        
        
        
      

    

in a terminal window

I have also tried

/usr/local/bin/ocaml

      

        
        
        
      

    

and is executed from the xterm window. All three give:

Bus Error

      

        
        
        
      

    

I have Xcode and X11 installed as README required.
