cant compile 4.2.1 on FreeBSD with domxml support

I am trying to install 4.2.1 on FreeBSD 4.4 STABLE. It continues to fail during make in domxml with the following: Making all in domxml /bin/sh /usr/ports/www/mod_php4/work/php-4.2.1/libtool --silent --mode=compile c -I. -I/usr/ports/www/mod_php4/work/php-4.2.1/ext/domxml -I/usr/ports/www/ mod_php4/work/php-4.2.1/main -I/usr/ports/www/mod_php4/work/php-4.2.1 -I/usr /local/include/apache -I/usr/ports/www/mod_php4/work/php-4.2.1/Zend -I/usr/l ocal/include/libxml2 -I/usr/local/include -I/usr/local/include/mysql -DHARD _SERVER_LIMIT=512 -DDOCUMENT_LOCATION="/usr/local/www/data/" -DDEFAULT_PATH= "/usr/local/bin:/bin:/usr/bin" -DACCEPT_FILTER_NAME="httpready" -DMOD_SSL=20 8106 -DEAPI -DEAPI_MM -DUSE_EXPAT -I/usr/ports/www/mod_php4/work/php-4.2.1/T SRM -O -pipe -I/usr/local/include -prefer-pic -c php_domxml.c php_domxml.c: In function `zif_domxml_doc_get_element_by_id': php_domxml.c:2675: warning: passing arg 2 of `xmlHashScan' from incompatible pointer type php_domxml.c: In function `zif_domxml_doc_ids': php_domxml.c:3292: warning: passing arg 2 of `xmlHashScan' from incompatible pointer type php_domxml.c: In function `zif_xmldoc': php_domxml.c:3309: `xmlDoValidityCheckingDefaultValue' undeclared (first use in this function) php_domxml.c:3309: (Each undeclared identifier is reported only once php_domxml.c:3309: for each function it appears in.) php_domxml.c:3325: `xmlLoadExtDtdDefaultValue' undeclared (first use in this function) *** Error code 1 Stop in /usr/ports/www/mod_php4/work/php-4.2.1/ext/domxml. We have installed 4.2.1 on our linux machines without any problems but just cant get it to work on FreeBSD. We have tried installing from the FreeBSD port and also directly from the source code, but get the same results. Can anyone shed some light on what the problem could be? Thanks, Rob
