title: RVM Does Not Install Ruby 1.9.2 on Snow Leopard: 'Error running 'make '
body: <p>When I try to install Ruby 1.9.2 on Snow Leopard using:</p>
  
  <pre><code>rvm install 1.9.2
  </code></pre>
  
  <p>I get the following:</p>
  
  <pre><code>ERROR: Error running 'make ', please read /Users/mary/.rvm/log/ruby-1.9.2-p180/make.log
  ERROR: There has been an error while running make. Halting the installation.
  </code></pre>
  
  <p>So, I check out make.log. The end of it reads:</p>
  
  <pre><code>readline.c: In function ‘username_completion_proc_call’:
  readline.c:1386: error: ‘username_completion_function’ undeclared (first use in this 
  function)
  
  readline.c:1386: error: (Each undeclared identifier is reported only once
  readline.c:1386: error: for each function it appears in.)
  make[1]: *** [readline.o] Error 1
  make: *** [mkmain.sh] Error 1
  </code></pre>
  
  <p>I have consulted other answers to this question, and done everything suggested there:</p>
  
  <ul>
  <li>XCode is installed.</li>
  <li><p>The end of my .bash_profile has the following line added to it:</p>
  
  <pre><code>[[ -s "$HOME/.rvm/scripts/rvm" ]] &amp;&amp; source "$HOME/.rvm/scripts/rvm"
  </code></pre></li>
  </ul>
  
  <p>I have tried updating readline, but no matter what, I continue to get the error message about running 'make.'</p>
  
  <p>The output of rvm info is the following:</p>
