PHP 4.3.3, use system regex with apache2

hi everyone, not sure if this is the right e-mail, but here goes i'm trying to build php so it uses the system regex library and not the the bundled one, and i have apache 2 and am using slackware 9.0 so far i have tried this configure command, but it doesn't work ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-bz2 --with-gd --enable-ftp --with-mysql-sock --with-ttf --with-freetype-dir --with-t1lib --enable-calendar --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib --with-zlib-dir=/usr/local/lib --with-regex=system i heard that it the apsx thing overrides the regex command so i then this ./configure --with-mysql --with-bz2 --with-gd --enable-ftp --with-mysql-sock --with-ttf --with-freetype-dir --with-t1lib --enable-calendar --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib --with-zlib-dir=/usr/local/lib --with-regex=system still no go, so i looked at the install directions and configure's help and it seems that for apache1 i should use --with-apache[=DIR], but i see no such flag for apache2 so how do i get this done, i'm trying to get the mapserver to work, and it won't even configure until php uses the system regex instead of the bundled one
