Berkeley DB version 1 is no longer supported

Hi,

I am trying to compile the Exim MTA by hand (yes, this is a release
candidate I want to test so it's not part of the ports) and I am getting
this error:

> clang -g -DMACRO_PREDEF macro_predef.c
> In file included from macro_predef.c:12:
> In file included from ./exim.h:535:
> ./hintsdb.h:461:4: error: Berkeley DB version 1 is no longer supported
> #  error Berkeley DB version 1 is no longer supported
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I am running FreeBSD 13-RELEASE.
Now, for the life of me, I cannot figure out where this Berkeley DB is
installed and how to upgrade it.
What I am seeing installed is databases/db5 (which is also marked for
DEPRECATION) come June 2022.

SOS!
