I have enabled the Zend repos and have it installed. The server control panel is working just fine but apache does not start. It complains of an unknown module config_unixd. I've checked the google and have come to the conclusion that the apache runtime util (apr) provided by F18 is different from that used in the Zend Server CE build. If that is the case, what can be done to get this going? If not, I'll take any other suggestions to get this going.
