That is out of date.  The issue in question comes from r7560.
Subversion no longer includes db.h, as explained by this excerpt
from that revision's log message:

  Replace #include <db.h> with:
  #define APU_WANT_DB
  #include <apu_want.h>

As i understand it, this change was the sledgehammer they used to
solve the "db-discovering code is borked" problem.

apr doesn't use Apache anything; apr and apr-util sit below
Apache and can be and are used without Apache even being
installed.  Before i made apr use db4, it was using the db in
NetBSD's libc.  I don't know what it did on Linux, for example,
or if it built at all.
