building fail on redhat 7.2 with gcl 2.4.1

Hi,
I am trying to build maxima 5.6 with gcl 2.4.1. Here is the end of the make 
output:

I have a redhat 7.2 linux. I compiled gcl from source. My maxima-5.6/configure
file is:

#!/bin/sh
# edit next few lines
# GCLDIR should be where gcl was built, and the o/*.o lsp/*.o etc must be
# there to link with maxima
GCLDIR=/usr/local/src/gcl-2.4.1
# the directory where this file is, and where you will build maxima
# could use
#MAXDIR=/home/wfs/cvs/maxima
MAXDIR=`pwd`
# where to put some maxima .el files
#EMACS_SITE_LISP=/usr/local/lib/emacs/site-lisp
EMACS_SITE_LISP=/usr/share/emacs/20.7/site-lisp

# determines where to install
# PREFIX_DIR=/usr/local puts things in /usr/local/lib/maxima-x.y
# and /usr/local/bin
PREFIX_DIR=/usr/local
INFO_DIR=${PREFIX_DIR}/info
MAN_DIR=${PREFIX_DIR}/man/man1
