title: PECL install fails
body: <p>I have browsed every Google result, read all the forum posts about this error, but I cannot solve it.</p>
  
  <p>When using PECL install for anything, I always end up getting this error:</p>
  
  <pre><code>checking whether the C compiler works... configure: error: cannot run C compiled programs.
  </code></pre>
  
  <p>Everything else succeeds up to that point them bam!</p>
  
  <p>I'm using CentOS 4.3, PEAR is the latest stable version, GCC is a stable and recent version. Everything is working as it should, but the C compiler always seems to error. I've tried to make tmp have the right privilages for the operation by temporarily enabling it using:</p>
  
  <pre><code>mount -o remount,exec,suid /tmp
  </code></pre>
  
  <p>But that doesn't work.</p>
  
  <p>I've literally tried everything that has been suggested by to no avail. Any ideas?</p>
