title: RVM install ruby from local source
body: <p>I can't believe the this isn't a more frequently asked question.</p>
  
  <p>I want to install ruby 1.9.2, and I want it as part of my RVM installation. The link for 1.9.2 has since 404'd on the ruby-lang site, so I copied the tar.gz from the ruby github page, rezipped it into a tar.bz2 like rvm requires and dropped it into <code>~/.rvm/archives</code></p>
  
  <p>However, every time I call <code>rvm install 1.9.2-p320</code> it deletes the source tar.bz2 from <code>~/.rvm/archives</code> and tries to redownload the tar.bz2 from the ruby-lang site.</p>
  
  <p>The <code>--force</code> and <code>--disable-binary</code> options do nothing to prevent the deleting and redownloading attempts.</p>
  
  <p>Is there a way to point rvm explicitly to the source tar.bz2? I'd like to avoid compiling from source myself and then copying the directory into wherever rvm needs it.</p>
  
  <p><strong>Note:</strong> It looks like the ruby-lang ftp server is just down for the moment which explains why the download keeps failing, but my question still stands as this seems like good functionality for rvm to have.</p>
