When compiling with the following configuration:

./configure \
--prefix=/usr/local \
--with-config-file-path=/etc/apache-ssl/conf \
--with-apxs=/usr/bin/apxs \
--with-openlink=/usr/local/openlink \
--without-mysql \
--enable-track-vars

the following error is produced:

Yet when using the same configuration with PHP-4.0.0, no error is produced.  Any suggestions?
