[Mediawiki-l] Undefined symbol error

[Thomas Cherry]

I'm running a 1.6.2 mediawiki server (which I recently upgraded) and  
I'm getting an error while trying to load some pages.  The pages with  
problems never show up, in fact the browser window is blank.  In my  
apache log I find the following line for every attempt to load the  
page in question:

/libexec/ld-elf.so.1: /usr/local/lib/php/20020429/pcre.so: Undefined  
symbol "php_addslashes_ex"

I also get the same error when running refreshLinks.php

# php refreshLinks.php
Refreshing link table.
Starting from page_id 1 of 1838.

/libexec/ld-elf.so.1: /usr/local/lib/php/20020429/pcre.so: Undefined  
symbol "php_addslashes_ex"

I'm guessing that there is some "bad" data in one or some of my  
records, does anyone have an idea how I can solve this?
