php cannot find mysql libs and includes after portupgrade

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 <snip> 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? Sven
