Ruby on Rails

Hey anyone,

I'm using htmldoc-0.2.3 on ruby 1.8.7 and I'm struggling to get it
working. I've created the following ruby file and get the following
error:
------
require 'rubygems'
require 'htmldoc'

pdf = PDF::HTMLDoc.new

pdf.set_option :outfile, "/tmp/outfile.pdf"
pdf << 'test text'

if pdf.generate
puts "Successfully generated a PDF file"
else
puts pdf.result[:output]
end
----
Error:

/Users/dandan/.rvm/gems/ruby-1.8.7-p302/gems/htmldoc-0.2.3/lib/
htmldoc.rb:182:in `execute': Invalid program path: htmldoc
(PDF::HTMLDocException)
from /Users/dandan/.rvm/gems/ruby-1.8.7-p302/gems/htmldoc-0.2.3/lib/
htmldoc.rb:154:in `generate'
from pdf.rb:17

To attempt to fix this I added
PDF::HTMLDoc.program_path = '/Users/dandan/.rvm/gems/ruby-1.8.7-p302/
gems/htmldoc-0.2.3'

Running the script again I get the output from pdf.result[:output]:
sh: /Users/dandan/.rvm/gems/ruby-1.8.7-p302/gems/htmldoc-0.2.3: is a
directory

Has anyone else experienced this problem and has a solution. I'm
guessing I'm giving the wrong program path but I'm not sure which path
I should be giving.

Thanks abundantly for any help!

Dan
