It looks like configure found the file db.h, which is human-readable
and good for getting the version (like it did), but when it tried to
link to the actual library (.so and .a in unix, .dll in windows?)
(-ldb45 is the switch that's failing, which is the linking)

You'd specify that path with -L in gcc.  Try adding this to your
CFLAGS environment.

    -llibrary
         Use the library named library when linking.

         The linker searches a standard list of directories  for
         the   library,   which   is   actually   a  file  named
         `liblibrary.a'.  The linker then uses this file  as  if
         it had been specified precisely by name.

         The directories searched include several standard  sys-
         tem directories plus any that you specify with `-L'.
