title: RVM fails to install Rubies
body: <p>Why is RVM failing to install ruby?</p>
  
  <p>My development machine died and I am recreating my development environment on another machine Cygwin 32 bit, Win 7 64 bit and RVM.  I've installed RVM using the standard <code>\curl -sSL https://get.rvm.io | bash</code> and by following this script <a href="http://blog.developwithpassion.com/2012/03/30/installing-rvm-with-cygwin-on-windows/" rel="nofollow">Installing RVM With Cygwin on Windows</a> and installing RVM with Ruby <code>\curl -sSL https://get.rvm.io | bash -s stable --ruby</code>. RVM seems to install successfully each time but when I try to install a version of Ruby using RVM I get this message: </p>
  
  <blockquote>
    <p>Searching for binary rubies, this might take some time. No binary

    with compilation. Please read 'rvm help mount' to get more information

  <p>I do not remember in my previous, same config, setup having any issues with RVM. I had multiple versions of Ruby installed and was able to move between them with RVM.</p>
  
  <p>I installed Ruby 1.9.3 successfully with the Cygwin setup program outside of RVM. Similar error with Cygwin 64 bit.</p>
  
  <p>I have installed and uninstalled Cygwin several times, the same with RVM without success. After much searching and trial and error I've begun focusing on this <code>cygwin/unknown/i386/ruby-2.0.0-p353</code> Is it possibly a PATH environmental variable issue? Thanks</p>
