Error checking Berkeley DB versions on Intel Mac

[Chris Wilkes]

I'm trying to compile bogofilter on an MacBookPro (the new Apple laptop
with the Intel chip) and I'm getting the following error when running
  ./configure --with-libdb-prefix=/sw/
(the "fink" program stores its files under /sw/, which is where my
Berkeley DB 4.3 files are located)

 checking how to link with libdb... -L/sw//lib -ldb
 checking db and dependent libraries... -L/sw//lib -ldb 
 checking if a program can be linked against Berkeley DB and run... yes
 checking if Berkeley DB header and library versions match... no
 configure: error: db.h header file and db library version do not match.

Here's the part from the config.log file.  Any ideas?
