Build Error

I have followed the instructions exactly on the FAQ page, but am getting the
following error:

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I../../insight-6.8/bfd -I. -
DTRAD_CORE -I. -I../../insight-6.8/bfd -I../../insight-6.8/bfd/../include -W -
Wall -Wstrict-prototypes -Wmissing-prototypes -Werror -g -O2 -c
../../insight-6.8/bfd/elf32-i386.c -o elf32-i386.o
../../insight-6.8/bfd/elf32-i386.c: In function 'elf_i386_relocate_section':
../../insight-6.8/bfd/elf32-i386.c:2635:16: error: variable 'warned' set but
not used [-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors

This has occurred in multiple installations with varying distro types (Ubunut,
Kubuntu, Xubuntu) and versions (10.11, 12.04 (beta)).
