Hello, this is the information I have been given from Dreamhost and from our HTML programmer:
Dreamhost says: "This installation requires the use of PEAR to get the PECL extension setup. For more info about PEAR at DreamHost, check out our wiki article here: http://wiki.dreamhost.com/PEAR."
The programmer says: “u basically need LAMP (linux apache mysql php) server administrator who is expert in installing and configuring components for LAMP.”
Does this answer your question?
