title: Why does configure say no C compiler found when GCC is installed?
body: <p>I am trying to make <a href="http://www.sphinxsearch.com">Sphinx</a> from source on a 32-bit CentOS 6 VPS.</p>
  
  <p>When I run this command:</p>
  
  <pre><code>./configure --prefix=/usr/local/sphinx
  </code></pre>
  
  <p>I get this error output:</p>
  
  <pre><code>checking build environment
  --------------------------
  
  checking for a BSD-compatible install... /usr/bin/install -c
  checking whether build environment is sane... yes
  checking for a thread-safe mkdir -p... /bin/mkdir -p
  checking for gawk... gawk
  checking whether make sets $(MAKE)... yes
  checking whether to enable maintainer-specific portions of Makefiles... no
  
  checking for compiler programs
  ------------------------------
  
  checking whether to compile debug version... no
  checking for gcc... no
  checking for cc... no
  checking for cl.exe... no
  configure: error: in `/home/gnotes/sphinx':
  configure: error: no acceptable C compiler found in $PATH
  See `config.log' for more details.
  </code></pre>
  
  <p>What I don't understand is that GCC is installed so why can't configure find an acceptable C compiler?</p>
  
  <p>Here's the output of yum:</p>
