+  The default BerkeleyDB provider for apr-util was changed from BerkeleyDB
+  5 (deprecated) to BerkeleyDB 1 from base libc. The change of version
+  results in a non-compatible database format.

+  After upgrading, you must rebuild all BerkeleyDB databases used by
+  apr-util (example: Apache databases created with `httxt2dbm -F db`
