The linker doesn't always know of /usr/local/lib. It (almost) always
know of /usr/lib (LIBPATH).

The solution is to tell the linker and cpp to look for libs and headers
in other places as well.

Your example (with working flags):

export CPPFLAGS="-I/usr/local/BerkeleyDB.4.1/include \
                 -I/your/path/to/openssl/include"
export LDFLAGS="-L/usr/local/BerkeleyDB.4.1/lib \
                -R/usr/local/BerkeleyDB.4.1/lib \
                -L/your/path/to/openssl/lib \
                -R/your/path/to/openssl/lib"

The '-L' flag tell the linker to search for libraries in the following
path. The libs found here are chosen before those in the standard
directories. The '-R' flag tells the runtime linker where to search
for libraries when the program is run.

If you include '-L', but not '-R' you often get errors when running
the sotfware compiled. It compiles ok, but doesn't have a clue where
to look for libraries it was compiled against.

On Linux replace '-R<path>' with '-Wl,-rpath,<path>'.
