problem installing 8.0.0beta5 on OS X 10.3

I'm trying to compile beta5 on osx 10.3.6
without success, I have XCode 1.5 installed.

Could you please give me instructions?
I have readline installed from fink.
Bison is there from Apple.

This is from the Terminal.app:
~/Desktop/postgresql-8.0.0beta5 (alpha) ./configure
--bindir=/usr/local/bin --mandir=/usr/local/share/man/ --enable-recode
--enable-syslog --enable-unicode-conversion --enable-multibyte
--with-includes=/sw/include/ --with-libraries=/sw/lib
checking build system type... powerpc-apple-darwin7.6.0
checking host system type... powerpc-apple-darwin7.6.0
checking which template to use... darwin
checking whether to build with 64-bit integer date/time support... no
checking whether NLS is wanted... no
checking for default port number... 5432
checking for gcc... gcc
checking for C compiler default output... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.

After removing line 2050 to 2077 in configure:

#############################
# Check the compiler produces executables we can run. If not, either
# the compiler is broken, or we cross compile.
echo "$as_me:$LINENO: checking whether the C compiler works" >&5
echo $ECHO_N "checking whether the C compiler works... $ECHO_C" >&6
# FIXME: These cross compiler hacks should be removed for Autoconf 3.0
# If not cross compiling, check that we can run a simple program.
if test "$cross_compiling" != yes; then
if { ac_try='./$ac_file'
{ (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
(eval $ac_try) 2>&5
ac_status=$?
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); }; }; then
cross_compiling=no
else
if test "$cross_compiling" = maybe; then
cross_compiling=yes
else
{ { echo "$as_me:$LINENO: error: cannot run C compiled programs.
If you meant to cross compile, use \`--host'." >&5
echo "$as_me: error: cannot run C compiled programs.
If you meant to cross compile, use \`--host'." >&2;}
{ (exit 1); exit 1; }; }
fi

echo "$as_me:$LINENO: result: yes" >&5
echo "${ECHO_T}yes" >&6

I was able to configure, at least I got:
All of PostgreSQL successfully made. Ready to install.

but then:

I did remove XCode 1.5, installed XCode 1.2, no difference. 8(

Well If you have an idea, I'd welcome it 8)

Have a nice day!
