REX usage

[trash at jipe-world.com (Jipe)]

Hi list,

I'm trying to use the REX method pattern_create but I get the following 
error, I think this is a kind of "include/require" mistake.

jipe at gadabou ~ $ cd trunk/lib/
jipe at gadabou ~/trunk/lib $ cat test.rb

#!/usr/bin/ruby
require "rex.rb"
print Rex::Text::pattern_create(15, Rex::Text::Numerals)

jipe at gadabou ~/trunk/lib $ ./test.rb
./rex/text.rb:759:in `converge_sets': undefined method `length' for 
57:Fixnum (NoMethodError)
         from ./rex/text.rb:755:in `converge_sets'
         from ./rex/text.rb:593:in `pattern_create'
         from ./test.rb:3
jipe at gadabou ~/trunk/lib $


Thanks for your help
