Hi there,

A friend of mine tried using RedCloth on Windows as part of a project
I introduced hin to, but RedCloth failed to require. This is what he 
got:

======================================================================

======================================================================

We found out that there isn't any file called
ext/redcloth_scan/1.9/redcloth_scan.so. It's just
ext/redcloth_scan/redcloth-scan.so (without the "1.9" part). This code
in redcloth.rb isn't necessary:

======================================================================
  prefix = Config::CONFIG['arch'] =~ /mswin|mingw/ ?
"#{Config::CONFIG['MAJOR']}.#{Config::CONFIG['MINOR']}/" : ''
  lib = "#{prefix}redcloth_scan"
  require lib
======================================================================

It should be simply 'require "redcloth_scan"', which works fine for
him after he changed the file accordingly.

My friend is running Windows 7 with RubyInstaller's 1.9.2-p290, but
doesn't use the devkit as he has a local MinGW/MSYS environment
(MSYS-Git, to be exact) already set up. Note I don't use Windows (Arch
Linux user) and I just forward what he told me and I diagnosed from 
that.

Valete,
Marvin
