Ez publisher

Anyone tried this piece of code? I've been looking around for such a publishing service, and finally found ez-publish. (http://publish.ez.no) Anyway, I tried to install it, but I always get an error-message telling med Call to undefined function: xmltree() in ezarticle/classes/ezarticlerenderer.php on line 40 so, I look into the documentation, which tells me that mod_php4 has to be compiled with the --with-dom=<path-where libxml2.x is installed. I'm sure I've installed libxml (in /usr/local), and I've even tried to compile/install mod_php4 several times with different configure args, but still without luck. Does anyone know how I shall get mod_php4 (4.0.4pl1 in fact) configured the right way? the platform in FreeBSD4.1 for alpha, and I've installed mod_php4 from the ports-tree. Lars Løvdal
