title: Cannot install ruby using RVM in Cygwin - curl SSL cert problem
body: <p>I'm trying to install ruby using RVM in Cygwin, but I'm getting the error:</p>
  
  <blockquote>
    <p>curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
    error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

  <p>i've looked at this question: <a href="https://stackoverflow.com/questions/6414232/curl-certificate-error-when-using-rvm-to-install-ruby-1-9-2">Curl Certificate Error when Using RVM to install Ruby 1.9.2</a></p>
  
  <p>but unfortunately the solution doesn't work for me because <code>curl-config --ca</code> doesn't show anything. I checked with <code>curl-config --configure</code> and it seems the package was compiled with the <code>--without-ca-bundle</code></p>
  
  <p>how can I work around this?</p>
