Call-time pass-by-reference deprecation errors

[<li...@jm...>]

hi, i use xpath all the time, but i'm a little new to php.
i'm using the latest version of php.xpath [2.1 (beta)], 
and whether i include() it or require() it, i get copious [well, ten] 
errors of the following sort:

> Warning: Call-time pass-by-reference has been deprecated - argument 
> passed by value; If you would like to pass it by reference, modify the 
> declaration of [runtime function name](). If you would like to enable 
> call-time pass-by-reference, you can set allow_call_time_pass_reference 
> to true in your INI file. However, future versions may not support this

there was no INSTALL or README in the top level of the src directory; 
am i missing a step, or does this look like  php version-mismatch?

thanks in advance,
