Using doc/programmer/README.osx from CVS on 0.93.3.1 on OSX 10.3.6
with Berkeley DB 4 installed by fink (same result with
--with-libdb-prefix, without -db, is this a typo?):

$ ./configure --with-libdb-prefix-db=/sw/include/db4
[...]
checking how to link with libdb... -ldb
checking db and dependent libraries... -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.

This is because /usr/include/db.h doesn't refer to Sleepycat's
version, which is also true for OpenBSD, FreeBSD and probably NetBSD
too. The following works for me with 0.93.3.1:

OpenBSD 3.5 (db4 from packages):
env CPPFLAGS=-I/usr/local/include/db4 LDFLAGS=-L/usr/local/lib ./configure

FreeBSD 4.10 (db4 from ports):
env CPPFLAGS=-I/usr/local/include/db4 LIBS=-ldb4 LDFLAGS=-L/usr/local/lib ./configure

Mac OS X 10.3.6 (db4 from fink):
env CPPFLAGS=-I/sw/include/db4 LDFLAGS=-L/sw/lib ./configure

There's no point (?) in using --with-libdb-prefix in this case.
What's needed is probably a "--with"-flag for libdb's include dir
(bogofilter looks for <db.h> and not <db[34]/db.h>) to prevent loading
the system /usr/include/db.h. Notice that FreeBSD names the library
libdb[34], whereas OpenBSD and OS X uses libdb.

The "how to link with libdb" result is misleading using the above for
FreeBSD: it reports "checking how to link with libdb... -ldb", but
there's no libdb, it's libdb[34]. Would it have found -ldb[34]
automatically if no environment tampering had taken place?

Btw, if things should be kept simple in README.osx: Apple's Developer
tools uses gcc, I think xlc users can figure out CC=xlc. Also, "HP
Gnome Desktop" (HP?) is probably far less common than fink.
