In general you cannot mix and match BDB utilities, you must use the 
exact same version that was used to compile OpenLDAP. If you're using a 
Symas CDS build then all of the proper utilities are included in the 
package. If you're using a package created by someone else then you 
should get the utility from them. (Personally, I wouldn't trust a 
package from someone else if they were too negligent to provide all the 
needed utilities in the first place.)

You are clearly using the wrong version.

The "Permission denied" errors probably indicate that you tried to run 
db_recover while slapd was running. You have to stop slapd and insure 
that no programs have any of the database files open before you can run 
db_recover. After you get hold of the right version of the utility and 
make sure that no programs are using the database these problems should 
go away.
