with-iconv snow Leopard

Hi,

I trie to recompile php 5.2.11 on OS S Snow leopard without success.
(I need the < 5.3 version for the magento open source installation)

Here are my settings:

./configure \
--prefix=/usr/local/php5 \
--with-iconv-dir=/usr/ \
--with-apxs2 \
--enable-pdo \
--enable-mbstring \
--enable-gd-native-ttf \
--with-freetype-dir=/usr/local/lib \
--with-t1lib=/usr/local/lib \
--with-xpm-dir=/usr/X11R6 \
--with-gd \
--with-zlib \
--with-jpeg-dir=/usr/local/lib \
--with-png-dir=/usr/local/lib \
--with-curl \
--with-mcrypt \
--with-mysql-sock=/tmp/mysql.sock \
--with-pdo_mysql=/usr/local/mysql/bin/mysql_config \
--with-mysql=/usr/local/mysql/ \
--with-mysqli=/usr/local/mysql/bin/mysql_config \
--enable-cli \
--with-pcre-dir=/usr/local/


I allways get the following error:

Undefined symbols:
   "_libiconv_open", referenced from:
       _do_convert in gdkanji.o

ld: symbol(s) not found

make: *** [libs/libphp5.bundle] Error 1

When I use --without-iconv \
the installation works fine.

I tried many many variants like:

patching the iconv.c     (change libiconv to iconv)

use --with-iconv=/usr/ \
use --with-iconv=/usr/local \  with self compiled iconv

Nothing helps!!!

I think its a 32 bit to 64 bit problem.
But I can get to a solution or work around.

So please help. Any hint is welcome!
