Hmm, as a distro packager, I really don't like seeing whole bunch of
external code being integrated that way in modules.

Why ?
Because it makes packages (and fixes) much more harder to fix in case
something needs to be fix in the external code. 

The best example is zlib which was copied in a LOT of places (3 times in
kernel, dozen of time in various apps) and when the first security bug
was raised in zlib, it tooks about 6 months to get the situation cleaned
correctly. Moreover, since it was statically link with those programs,
doing the security fix was really a pain.

Dynamic linking is really a great think when maintaining distro (or for
ports to new arch, etc..). So I would really prefer you don't come with
your own copy of db4 :(

Of course, if db4 file format is known to not change during the entire
4.x branch, it is not really a problem :)
