Do not use the version of db that was distributed on
the Net2 tape. It is riddled with bugs.
Do get the latest distribution of db via anonymous
FTP from ftp.CS.Berkeley.EDU. The file
ucb/4bsd/db.tar.Zis a symbolic link that always points to the latest distribution.
That file is a compressed, tar(1) archive and can be extracted
like this:
% zcat db.tar.Z | tar xvf -
The result will be creation of a new directory with the name
db.something, where the something is the
latest version number.
To compile the database library, you need to change into that
directory. A listing of its contents might look like this:
Makefile.inc changelog include test
PORT db man
README docs mpool
btree hash recno
Inside the db distribution directory is a subdirectory
called PORT. In order to compile, change first into that subdirectory
and list the files there:
% cd PORT
% ls
Makefile dgux.5.4 osf.1.0.2 sunos.4.1.1
README hpux.8.07 osf.1.3 sunos.4.1.2
aix.3.2 hpux.9.01 osf.2.0 sunos.4.1.3
bsd.4.4 include ptx.2.0 sunos.5.2
bsdi.1.0 irix.4.05F sinix.5.41 ultrix.4.2
clib linux solaris.2.2 ultrix.4.3
Always read the README file first. Then select the
directory that is most suitable for your machine, say, sunos.4.1.3.

Change into it. It will look kind of bare, but that is okay.
% cd sunos.4.1.3
% ls
Makefile clib include sys
If you elected to include support for both NDBM and NEWDB in
Section 33.1, "Enable at Compile Time", you will need to make Makefile
writable and edit it. (If you selected only NEWDB,
you should skip this step.)
This is necessary because your system's ndbm(3) will confict
with the internal ndbm of db and cause sendmail
to fail in spectacular ways.
Make Makefile writable, edit it, and remove all references
to ndbm.o. Then remove the file from
the include directory:
% rm include/ndbm.h
