 def caveats; <<-EOS
   For 10.5 and Apache:
    Apache needs to run in 32-bit mode. You can either force Apache to start 
    in 32-bit mode or you can thin the Apache executable.
   
   To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php5_module    #{prefix}/libexec/apache2/libphp5.so

    The php.ini file can be found in:
      #{prefix}/etc/php.ini
