Installation problem - BerkeleyDB installed but not found

Hello,

I'm having some problems installing subversion (1.3.0). Currently, I
have BerkeleyDB 4.3.0 installed in /usr/local/BerkeleyDB.4.3/

However, when I run configure, I get the following messages:

--
checking for Berkeley DB 4.3 in /usr/local/BerkeleyDB.4.3...
checking db43/db.h usability... no
checking db43/db.h presence... no
checking for db43/db.h... no
--
In my BerkeleyDB.4.3 directory, I only have the following directories:
bin, docs, include and lib.
Am I missing something here?
Thanks, and sorry for the newbie questions.
