The configure script is probably looking in /usr/local for the Berkeley DB headers and libraries, which are normally installed on Mac OS X under /usr/local/BerkeleyDB/

You should be able to fix this problem by typing the following:

$ sudo ln -s /usr/local/BerkeleyDB/include/* /usr/local/include/
$ sudo ln -s /usr/local/BerkeleyDB/lib/* /usr/local/lib/

The config script should now find the BDB files without any additional options or variables.

I tried with
ln -s /usr/local/BerkeleyDB/include/* /usr/local/include/
ln -s /usr/local/BerkeleyDB/lib/* /usr/local/lib/

but still same problem
