require SecurityError

Hi,

I'm sure this must have been asked before, but my Googling didn't turn
up anything: in my mod_ruby script I simple want to require a class file
I've written.  The method is:

  def displaySections
    $:.unshift(File.expand_path("../client/"))
    require 'soap/rpc/driver'
    require 'page'
    .
    .
    .
  end

Ruby throws a wobbly trying to require 'page' though: the error (from
Apache's log) is:

[Wed Jan 26 09:58:57 2005] [error]
mod_ruby: /home/rjt/sara/trunk/src/public_html/sections.rbx:32:in
`require': Insecure operation - require (SecurityError)

What do I have to do to require this file?  Temporarily making the dir
read-only to everyone makes no difference.

Cheers,

Richard.
