Help with changing include_path variable

Hello, I need your help, please read thread below. I was told from dreamhost to post this in here and someone would help me. I have no clue what they are talking about and need step by step instructions Please.

I installed Kayaka Help desk software and it’s having conflicts with settings on dreamhost. The Error I receive when I try to send out an reply in the Kayako system.

[Runtime Notice]: Assigning the return value of new by reference is deprecated (php/SMTP.php:127)

What Kayako tech said about the error:

This doesn’t seem to be an issue with our product. Our SMTP files are in __swift/thirdparty/XPM/PHP5/SMTP5.php whilst the error is for php/SMTP.php. From the phpinfo, I have found ‘include_path’ is pointing to this url: ‘.:/usr/local/lib/php:/usr/local/php5/lib/pear’, PEAR that is causing the conflict with include_path.[/quote]

Please Change the include_path to “.”. In case you have any other applications utilizing PEAR, just ensure that they point to the correct directory otherwise you might end up breaking them.[/quote]
