For anybody following: sorry, my bad. It turns out I hadn't set CPPFLAGS
and LDFLAGS during the configure to use /usr/local/{include,lib}. When
that's done, this works (in the sense that libdovecot.so is now linked with
libcdb!).

I'm not so sure that this is the best place to link libcdb in, though, but
for an expedient fix, it works.... Would appreciate somebody more familiar
with the code weighing in on this one.

Well, it was never supposed to be linked to anything except the dict binary,
allowing it to be used via the dict proxy. Changed:

Thanks, Timo. Is this the only patch that needs to go in for the current
version (2.2.15)? I've applied this to 2.2.15, and configured and compiled
as before:

CPPFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib ./configure
--with-cdb
make

and I still get the same errors.
