configure insists on libdb-3.1, when I have libdb-4.0

[Ian McDonald]

Hi,

Still trying to install Cyrus. The current problem is the Berkeley db
software: I have compiled and installed the latest version (4.0).
'configure', on the other hand, misses that version and insists on using
3.1;

./configure --with-auth=unix --without-krb --with-com_err=yes --with-dbdir=/
usr
(Excerpt from ./configure output.)
checking for vprintf... (cached) yes
checking for db_create in -ldb-4.0... (cached) no
checking for db_create in -ldb-4... (cached) no
checking for db_create in -ldb4.0... (cached) no
checking for db_create in -ldb4... (cached) no
checking for db_create in -ldb-3.3... (cached) no
checking for db_create in -ldb3.3... (cached) no
checking for db_create in -ldb-3.2... (cached) no
checking for db_create in -ldb3.2... (cached) no
checking for db_create in -ldb-3.1... (cached) yes
checking duplicate db database backend... db3_nosync
checking mboxlist database backend... db3

But I don't even have db3:

As a result, make crashes:

What is the db_create check? What do I need to do to get ./configure to see
DB 4.0?

Thanks,

Ian
