Incompatibility of iconv for PHP 5.2.13 under Mac OS X

I'm confused with this when I compiled 5.2.13 of PHP under Mac OS X Snow Leopard. I did update by downloading and compiling a new version of iconv at http://www.gnu.org/software/libiconv/ and compile it by running

./configure --prefix=/usr/local

When I compile PHP with the following "configure" params as

CFLAGS="-arch x86_64 -g -Os -pipe -no-cpp-precomp" CCFLAGS="-arch x86_64 -g -Os -pipe" CXXFLAGS="-arch x86_64 -g -Os -pipe" LDFLAGS="-arch x86_64 -bind_at_load" ./configure  --prefix=/opt/local --mandir=/usr/share/man --infodir=/usr/share/info --with-config-file-path=/etc/ --enable-bcmath --enable-ctype --enable-dom --enable-fileinfo --enable-filter --enable-hash --enable-json --enable-libxml --enable-pdo --enable-phar --enable-session --enable-simplexml --enable-tokenizer --enable-xml --enable-xmlreader --enable-xmlwriter --with-bz2=/opt/local --with-mhash=/opt/local --with-pcre-regex=/opt/local --with-readline=/opt/local --with-libxml-dir=/opt/local --with-zlib=/opt/local --disable-cgi --with-ldap=/opt/local --with-apxs2=/usr/sbin/apxs --with-mysqli=/opt/local/lib/mysql/bin/mysql_config --with-openssl --with-mcrypt=/opt/local/ --with-mysql=/opt/local/lib/mysql/ --with-curl=/opt/local --enable-mbstring --with-gd --with-jpeg-dir=/opt/local --with-png-dir=/opt/local --with-freetype-dir=/opt/local --with-t1lib=/opt/local --enable-gd-native-ttf --with-ttf=/opt/local --with-pgsql=/usr/local/pgsql/ --with-iconv=/usr/local 

And when I run "make" I do got these errors,

 I guess this is a bug from PHP in which it only base for the libiconv library under /usr/lib directory, and my fix for this is by copying the libiconv I have recently compiled from /usr/local/lib/ with the current one, which is the /usr/lib/libiconv.* files.
So I did,

cd /usr/lib

mkdir iconv_backup

mv libiconv.* iconv_backup

cp -rf /usr/local/lib/libiconv.* .

cp -rf iconv_backup/* /usr/local/lib/

Now, running make compiles the source code of PHP successfully.

Caveat for this, my purpose of switching the libiconv files is because I have Adium and Adium isn't compliant with the libiconv in which I have recently compiled as x86_64 architecture or 64 bit, so having them under /usr/lib/iconv_backup, I run Adium thru terminal by /Applications/Adium.app/Contents/MacOS/Adium and it works good now.

Hope this helps!
