Cannot make 4.2.1 on FreeBSD with domxml

We have been unsuccessful trying to install the 4.2.1 port onto FreeBSD 4.4 STABLE when we add domxml support. The same configuration compiles and runs fine on our Linux machines, so was wondering if anyone has any idea what the problem is. The following is the output from the make: 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.
