Cannot build libphp5.so with the right version of libxml2

Hi, I'm installing PHP 5.3.6 with Apache HTTP 2.2.21 on a 64-bit centos platform (Linux 2.6.18-194.el5) to use with the Horde 4 platform (webmail). The system version of libxml is 2.6.26 , it is installed under /usr/lib64 (and /usr/lib), but Horde needs a 2.7 release of libxml, so I installed release 2.7.8 under /usr/local/lib (with includes under /usr/local/includes/libxml2) but libphp5.so gets compiled with the includes from /usr/local/includes/libxml2 and linked with /usr/lib64/libxml2.so and I don't know how to convince ld to use the right library. I don't have any error message from configure or make but httpd does not start with the following message: --------------------------------------------------------- Cannot load /www/httpd/modules/libphp5.so into server: /www/httpd/modules/libphp5.so: undefined symbol: xmlTextReaderSetup --------------------------------------------------------- I checked that xmlTextReaderSetup is defined in the includes for release 2.7 of libxml but not 2.6 Here is how I run configure: ------------------------------------------------------------ ./configure --prefix=/www/php-5.3.6 --with-apxs2=/www/httpd-2.2.21/bin/apxs \

              --with-openssl --with-ldap \
              --with-mysql \
              --enable-ftp \
              --with-libxml-dir=/usr/local/lib \
              --with-libdir=lib64 \
              --with-zlib \
              --with-imap --with-mcrypt  --with-kerberos --with-imap-ssl \
              --with-gd \

              --with-oci8=instantclient,/www/oracle --with-iconv --enable-mbstring=all --enable-mbregex

------------------------------------------------------------- (if I remove "--with-libdir=lib64" , I get a make error for libmysqlclient which tries to use /usr/lib/mysql/libmysqlclient.so.15) Here is the output of lld for libphp5.so : ------------------------------------------------------------- ldd libs/libphp5.so
