HTTPClient::SSLConfig uses "puts" ¿?¿?

Hi, I’m using HTTPClient which uses OpenSSL.
I’ve realized that HTTPClient includes a class SSLConfig which prints
to the standard and error output when verifying a SSL certificate,
i.e:

# Default callback for verification: only dumps error.
def default_verify_callback(is_ok, ctx)
  if $DEBUG
    puts "#{ is_ok ? 'ok' : 'ng' }: #{ctx.current_cert.subject}"
  end
  if !is_ok
    depth = ctx.error_depth
    code = ctx.error
    msg = ctx.error_string
    STDERR.puts "at depth #{depth} - #{code}: #{msg}"
  end
  is_ok
end

I set “http_client.ssl_config.verify_mode = 0” to avoid exceptions
when the SSL cert is not valid (expires, autosigned…) but, anyway,
the error is printed to the error output:

STDERR.puts “at depth #{depth} - #{code}: #{msg}”

This is really annoying. Why does a library writes to standar/error
output by itself? It shouldn’t occur!

Is there any ellegant way to avoid it without the need of rewritting
the methods?

Thanks.

It’s even worse, there are more “puts” into the module:

/usr/local/lib/ruby1.9/gems/1.9.1/gems/httpclient-2.1.5.2/lib$ grep -r
puts *
httpclient/ssl_config.rb: puts “#{ is_ok ? ‘ok’ : ‘ng’ }:
#{ctx.current_cert.subject}”
httpclient/ssl_config.rb: STDERR.puts “at depth #{depth} -
#{code}: #{msg}”
httpclient/ssl_config.rb: STDERR.puts “at depth #{depth} -
#{code}: #{msg}” if $DEBUG
httpclient/ssl_config.rb: STDERR.puts ‘self signing CA’ if $DEBUG
httpclient/ssl_config.rb: STDERR.puts ‘middle level CA’ if $DEBUG
httpclient/ssl_config.rb: STDERR.puts ‘for server
authentication’ if $DEBUG
httpclient/ssl_config.rb: STDERR.puts(“cacerts loading failed”)
httpclient.rb: puts “redirect to: #{newuri}” if $DEBUG
httpclient.rb: STDERR.puts(“could be a relative URI in location
header which is not recommended”)
httpclient.rb: STDERR.puts("‘The field value consists of a single
absolute URI’ in HTTP spec")
httpclient.rb: puts “redirect to: #{newuri}” if $DEBUG
