Hm, this seems more a php/drupal issue.

http://drupal.org/node/1268858

Maybe thats the same issue on your site (drupal6: Block Translation module enabled)

Can you do an additional ldd check for libpcre?
(But I suspect this will not show any issues)
$> ldd /usr/local/libexec/apache22/libphp5.so
$> ldd /usr/local/bin/php*
