Hello, i must set the $stderr to an object that collects the data
inside a buffer. Is there something like pythons StringIO class ?

Have you tried StingIO

require 'stringio'

str = "hello world"
io = StringIO.new(str)

require 'stringio'

somestring = ""
out = StringIO.new(somestring,"w")

$stderr = out

# Above is untested...

That works for the most part. If you ever have trouble getting EVERYTHING
captured that's going to $stderr, just pipe all fd[2] output to a file:

# redirect stderr
$new_stderr = File:pen("capture_file");
$old_stderr = $stderr.clone
$stderr.reopen($new_stderr);

# ... STDERR is captured here ...

# restore stderr
$stderr.reopen($old_stderr);
$new_stderr.close

Now you have a file named "capture_file" which has everything that was sent to
stderr, even from code that didn't use Ruby's $stderr object.
