XML_RSS problems on OpenBSD

Hi All I have a problem with the above-mentioned package. I had a dev site running on a local windows PC with the above package working fine getting slashdot rss feed. I have now moved this site to a local OpenBSD 3.4 box with standard php and additional extensions including XML and DOM. The problem is that I just get an empty array fed back from the class, and all I can put it down to is "perhaps" the url-fopen-wrapper not being able to fetch http/ftp. Does anyone here know of this issue, is it to do with url-fopen-wrapper or something completely different. I'm not getting any warnings/notices or errors of any kind. The fopen part takes place in XML_Parser from what I can see. Any help or ideas would be much appreciated. Thanks in advance. -- Simon H
