Subject: Intermittant problem with Hpricot

I've run into a wierd problem with the Hpricot gem.  I don't know if
this is a problem with gems in general on my system, or if it's specific
to Hpricot, so I'm posting here.

Basically I have code as follows:
require 'rubygems'
require 'net/http'
require 'uri'
require_gem 'hpricot'

class Page
  def some_function(html_text)
    doc = Hpricot(html_text)
    doc.search("/html/body//img").each do |img|
       logger.debug("== Found an image: #{img} ==")
       src = img[/src="/]
       logger.debug("src = #{src}")
     end
  end
end


When the function is called, sometimes I get a message saying that
function Hpricot does not exist for the object of type Page.  this
continues for the entire programming session.

But sometimes, when I sit down to work on the project, the code works!
It continues working until I restart the Rails server (this is a Rails
project running on MacOSX).

Does anyone have any idea what might be causing this problem, and how to
correct it?

Alli
