I'm not sure your explanation is enough to justify the following
lines:

------------------------------------------------------------------------
$ sudo apt-get install libdb4.3
#
# Now on the system are present both db-4.2.52 (under /opt/foo) and
# db-4.3 (under /usr/).
#
$ export LD_LIBRARY_PATH=/opt/foo/lib
$ export CPPFLAGS=-I/opt/foo/include/
$ export LDFLAGS=-L/opt/foo/lib
$ ./configure

Can you explain the above behaviour?

I don't want to annoy you too much, I'm trying to be useful and to
learn something :-)
