Is there anybody on this list with:

ruby 1.8.3 or 1.8.4 and  
rio-0.3.4

who can run this:

require ‘rubygems’  
require ‘rio’  
p rio(??).mkdir.path

without getting an error message?

Thanks, good to have finally a test.  
You have a windows system, apparently?  
So my problem must be a linux-problem, a friend, also under linux, has  
the  
same problem:

/usr/local/lib/ruby/gems/1.8/gems/rio-0.3.4/lib/rio/ops/dir.rb:77:  
uninitialized constant RIO::Ops::FileOrDir::ExistOrNot (NameError)
