So this is a FreeBSD bug, which needs to be filed against FreeBSD. Exim
uses the system DB libraries and assumes that they're sane.
You can work around it by installing gdbm and setting USE_GDBM in the
Exim Local/Makefile; you should perhaps file a Ports bug to do this, if
it looks like the FreeBSD base bug isn't going to be fixed any time
soon.
See section 4.3 of The Exim Specification (doc/spec.txt), which tells
you to do something like:
USE_GDBM=yes
DBMLIB=-lgdbm
If Exim is having problems as a result of a system bug, but is the only
real user of the library, then Exim will be how it shows up on the
system, but there's nothing that can be done by Exim to fix this except
say "don't use the db library on that system, it's buggy, build Exim to
use something else".
