Your config.log extract doesn't match the error text above.

Configure finds -lresolv automatically. That's certainly not the cause of your 
problem.

Your configure session indicates that your system's default db.h came from 
BerkeleyDB 4.3 which is explicitly not supported. There's no indication of any 
software bug here; this ITS will be closed. Use the openldap-software mailing 
list if you need more help, these questions have been covered many times there 
and searching the list archives will give you the right answers.
