Error: shared library "mysqlclient.12" does not exist

Hej eksperter..

Jeg har installeret en FreeBSD 5.2 boks med MySQL 4.0 og Postfix 2 (begge installeret fra ports)..
Nu prøver jeg så at installere courier-imap porten med MySQL understøttelse, men får fejlen:

# make install WITH_MYSQL=yes
===>  courier-imap-2.2.0,1 depends on executable: gmake - found
===>  courier-imap-2.2.0,1 depends on file: /usr/local/bin/perl5.6.1 - found
===>  courier-imap-2.2.0,1 depends on shared library: crypto.3 - found
===>  courier-imap-2.2.0,1 depends on shared library: mysqlclient.12 - not found
===>    Verifying install for mysqlclient.12 in /usr/ports/databases/mysql40-client
===>  Returning to build of courier-imap-2.2.0,1
Error: shared library "mysqlclient.12" does not exist
*** Error code 1

Stop in /usr/ports/mail/courier-imap.


Hvad skal jeg gøre for at den kan finde ud af hvor mysql ligger??
