failed CVS maxima compilation with GCL

Hi,

I'm trying to compile maxima with GCL on a machine running Ubuntu
linux 8.10.

I compiled GCL from CVS today, apparently successfully:
GCL (GNU Common Lisp)  2.7.0 ANSI    Apr 26 2010 16:46:28

and the output when I try to compile maxima from CVS is below.  
What should I do?

Best wishes,
Rupert
