PHP 4.3.9 on Opteron

Hello, I wanted to compile php-4.3.9 as 64bit version under Suse Linux 9.2 64bit on a Dual Opteron system. These are my configure option ./configure --enable-shared --with-apxs=/usr/httpd/bin/apxs --without-pear --with-zlib=/usr/lib64 --with-bz2=/usr/lib64 \ -with-jpeg-dir=/usr/lib64 --with-gd --with-png-dir=/usr/lib64 --enable-gd-native-ttf --with-t1lib=/usr/lib64 \ --with-freetype-dir=/usr/lib64 --with-zip=/usr/lib64 --with-ldap=/usr/lib64 --with-openssl=/usr/lib64 \ --with-dom=/usr/lib64 --with-dom-xlst=/usr/lib64 --with-dom-exlst=/usr/lib64 --with-iconv=/usr/lib64 --enable-xlst But it fails, These are the last lines of the output : checking for GD support... yes checking for the location of libjpeg... /usr/lib64 checking for the location of libpng... /usr/lib64 checking for the location of libXpm... no checking for FreeType 1.x support... no checking for FreeType 2... /usr/lib64 checking for T1lib support... /usr/lib64 checking whether to enable truetype string function in GD... yes checking whether to enable JIS-mapped Japanese font support in GD... no checking for fabsf... yes checking for floorf... yes checking for jpeg_read_header in -ljpeg... yes checking for png_write_image in -lpng... yes If configure fails try --with-xpm-dir=<DIR> checking for T1_LoadFont in -lt1... yes checking for GNU gettext support... no checking for GNU MP support... no checking for hwapi support... no checking for Hyperwave support... no checking for iconv support... yes configure: error: Please reinstall the iconv library.
