What glibc are you using?

I had the same problem on Red Hat 6.2.

The short and skinny of what I remember is that during the linking
process while building PHP, it didn't link against pthreads, or linked
against the wrong one.

http://www.phpbuilder.com/mail/php-db/2000081/0117.php may shed some
light, as it all seems quite familiar.
http://www.phpbuilder.com/mail/php-db/2000081/0130.php looks worth a
look too.
