Compiling with IMAP

hello everyone! I'm getting the following compile-errors when trying to do with imap. any solution or suggestion on http://www.php.net/manual/en/ref.imap.php didn't work for me :-( I'm using OpenBSD with c-client installed from the ports-library (tried compiling manual too, seems to work fine) any ideas? thanks, andreas ./configure --with-mysql --with-apxs=/usr/local/apache/current/bin/apxs --wi th-gettext --with-imap --with-kerberos --with-imap-ssl .. ..
