php cannot find mysql libs and includes after portupgrade

[Sven Willenberger]

FreeBSD 5.2.1 and portupgraded mysql-client and server to 4.0.23a. Then
portupgrade -f lang/php4 and databases/php4-mysql. After this phpinfo()
and any php application using mysql no longer finds the include and lib
dirs and do not work.

>From phpinfo():
<snip>
extension_dir => /usr/local/lib/php/20020429
=> /usr/local/lib/php/20020429

mysql

MySQL Support => enabled
Active Persistent Links => 0
Active Links => 0
Client API version => 4.0.23a
MYSQL_MODULE_TYPE => none
MYSQL_SOCKET => /tmp/mysql.sock
MYSQL_INCLUDE =>
MYSQL_LIBS =>


but:

# ldd /usr/local/lib/php/20020429/mysql.so
/usr/local/lib/php/20020429/mysql.so:
        libmysqlclient.so.12
=> /usr/local/lib/mysql/libmysqlclient.so.12 (0x2815b000)
        libz.so.2 => /lib/libz.so.2 (0x2817e000)
        libcrypt.so.2 => /lib/libcrypt.so.2 (0x2818c000)
        libm.so.2 => /lib/libm.so.2 (0x281a5000)

mysql client itself connects without any problem, just php applications
cannot. Any ideas? Has anyone else come across this?
