title: rvm install 1.9.2 fails when running autoconf?
body: <p>when I run</p>
  
  <pre><code>rvm install 1.9.2
  </code></pre>
  
  <p>I get an error trying to run autoconf. This is the stacktrace:</p>
  
  <pre><code>kenmare:ruby-1.9.2-p0 lee$ rvm install 1.9.2-p0
  /Users/lee/.rvm/rubies/ruby-1.9.2-p0, this may take a while depending on your cpu(s)...
  
  ruby-1.9.2-p0 - #fetching 
  ruby-1.9.2-p0 - #extracted to /Users/lee/.rvm/src/ruby-1.9.2-p0 (already extracted)
  Running autoconf
  Error running 'autoconf', please check /Users/lee/.rvm/log/ruby-1.9.2-p0/autoconf.error.log
  Skipping configure step, 'configure' does not exist, did autoconf not run successfully?
  ruby-1.9.2-p0 - #compiling 
  Error running 'make ', please check /Users/lee/.rvm/log/ruby-1.9.2-p0/make.error.log
  There has been an error while running make. Halting the installation.
  </code></pre>
  
  <p>Any ideas? Thanks!</p>
  
  <p>UPDATE: Sorry it was late and didn't give some obvious info. I am on a mac running 10.6.4. The autoconf log says:</p>
  
  <pre><code>autoconf: no input file
  </code></pre>
  
  <p>To the answer regarding make, when I run</p>
  
  <pre><code>which make
  /usr/bin/make
  </code></pre>
  
  <p>And I have am running 1.8.7 successfully with rvm. I only receive this problem when installing 1.9.2.
  Thanks again!</p>
