Problem with PHP3 package!

["Stelios M." <steliosm_(_at_)_sdf_(_dot_)_lonestar_(_dot_)_org>]

I've installed OpenBSD 2.8 a few days ago during my upgrade. I also
installed the pre-compiled packages  mysql-3.22.32-pth and
php3-3.0.16-mysql. Everytime I try to start Apache I get this error:

  bash-2.04# apachectl start
   /usr/libexec/ld.so: httpd: libexpat.so.1.0: No such file or directory

  /usr/sbin/apachectl start: httpd could not be started

Is there anything I should also check ? I don't seem to have anywhere on
my system the required file (libexpat.so.1.0).

yours friendly,
