I've just wiped php4, Zend, and TSRM and checked out fresh versions
from CVS. Configuration script:

./configure \
  --with-apxs=/usr/local/apache/bin/apxs \
  --with-java \
  --with-mysql=/usr \
  --with-gd \
  --with-xml \
  --with-zlib \
  --with-curl \
  --with-sablot \
  --with-ibm-db2 \
  --with-iodbc=/usr/local \
  --enable-wddx \
  --enable-versioning \
  --enable-sysvshm \
  --enable-sysvsem \
  --enable-sockets \
  --enable-shmop \
  --disable-debug

configure and make proceed as normal, as does make install. Then,
upon running 'apachectl start'. I get this:

/home/torben/work/php4
shanna% apachectl start
Syntax error on line 209 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: undefined symbol: zend_ini_close_file
/usr/sbin/apachectl start: httpd could not be started


Line 209 of httpd.conf is:
LoadModule php4_module        libexec/libphp4.so

Nothing else has changed.
