configure appears to fail to put correct -l options in APXS_LDFLAGS for 
--with-ldap and --with-mysql, details below;

apache 1.3.12 with DSO
php-3.0.16
openldap 1.2.9
mysql 3.22.32

built php-3.0.16 with
./configure --with-apxs=/usr/local/apache/bin/apxs --with-xml \
 --with-ldap=/usr/local --with-config-file-path=/usr/local/apache

build and install appears to complete successfully, however apache (1.3.12) 
will not start, error message is

Cannot load /usr/local/apache/libexec/libphp3.so into server: ld.so.1: /usr/loca
l/apache/bin/httpd: fatal: relocation error: file /usr/local/apache/libexec/libp
hp3.so: symbol ber_free: referenced symbol not found

workaround appears to be to add -llber to APXS_LDFLAGS in Makefile after configure.

A similar problem occurs for mysql, adding -lmysqlclient to APXS_LDFLAGS appears
to fix it.

a quick look at configure.in suggests these should be added automatically, beyond
my knowledge to see why they are not.
