title: CakePHP Shell: Fatal error: Call to undefined function xcache_isset()
body: <p>I am having a strange problem right now with CakePHP. I haven't used the shell in sometime since I enabled XCache on Dreamhost, and now when I try to use the CakePHP Shell script I have, I get this error.. 
  Fatal error: Call to undefined function  xcache_isset() </p>
  
  <p>However, I don't have any errors/problems with my site, except for the shell it seems.. </p>
  
  <p>Any ideas how to fix this would be great! </p>
