compile help: cannot find -ldb

[csj <csj@mindgate.net>]

Using either apt-get source -b foo or dpkg-buildpackage after the 
fact, I have a number of debian source packages fail on me. In most 
cases the most conspicuous symptom is the following stderr line:

/usr/bin/ld: cannot find -ldb

What package am I missing? OR is it a ./configure problem?

Some bits of information about my setup:

(1) Source packages that have  failed to build: gtktalog , gnucash.
(2) libdb2-dev installed
