maxima install



Hi Maxima,

I built and installed maxima on my G4 Macintosh OS-X computer about a  
year
ago successfully. Recently I tried invoking maxima again and got the  
error:

% maxima
Maxima encountered a Lisp error:

  Error in SETF [or a callee]: Caught fatal error [memory may be  
damaged]

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
Error in SYSTEM::SETF-HELPER [or a callee]: The tag RETURN-FROM- 
DEBUGGER is undefined.

Fast links are on: do (use-fast-links nil) for debugging
Broken at CONDITIONS::CLCS-UNIVERSAL-ERROR-HANDLER.  Type :H for Help.
  1 (Abort) Return to top level.
dbl:MAXIMA>>

Any suggestions on error source and methods for fixing error.
I don't want to have to rebuild the whole system from scratch again.

Please contact me directly in addition to the listserv.

Thanks in advance,

Nick
