Can't Build 7.3.4 on OS X

I cannot build the latest release on OS X Jaguar.

Any ideas? Details below...

Running GCC 3.3 from Apple:

hunter% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1435)

Did just a vanilla './configure' and then make:

hunter% make
make -C doc all
gzip -d -c man.tar.gz | /usr/bin/tar xf -
for file in man1/*.1; do \
mv $file $file.bak && \
sed -e 's/\\fR(l)/\\fR(7)/' $file.bak >$file && \
rm -f $file.bak || exit; \
done
/bin/sh ../config/mkinstalldirs man7
mkdir man7
for file in manl/*.l; do \
sed -e '/^\.TH/s/"l"/"7"/' \
-e 's/\\fR(l)/\\fR(7)/' \
$file >man7/`basename $file | sed 's/.l$/.7/'` || exit; \
done
make -C src all
make -C port all
gcc -traditional-cpp -g -O2 -Wall -Wmissing-prototypes
-Wmissing-declarations -I../../src/include -c -o isinf.o isinf.c
