courier-imap authmysql mysql ./configure

[acsab]

I cannot seem to get courier-imap to ./configure --with-authmysql if i
./configure mysql --prefix=/usr/local/mysql. courier complains:
configure: error: --with-authmysql specified but no mysqlclient.so
configure: error: ./configure failed for authlib

I have checked the linkage:
libmysqlclient.so -> libmysqlclient.so.10.0.0
libmysqlclient.so.10 -> libmysqlclient.so.10.0.0

i had the same problem w/pqsql.so but i simply ln -s ...
the only way i can get courier to be happy is if i ./configure
with no prefix.

The mysql 3.23.52 rpms do not work either w/courier-imap
any help would be greatly appreciated.
Thanks very much!
