The latest patch for bitcoin fails to build if the deprecated bdb5 is not installed. Should be using dbd:18 The following Makefile change fixes the build problem: Change WALLET_USES= bdb:5+ sqlite:3 to WALLET_USES= bdb:18+ sqlite:3
This is part of the file format. It should be BDB:5. A change was committed as https://cgit.freebsd.org/ports/commit/?id=44e4316cdbc985045f69c6f46682edcc0ba63d6c
