I've just added them to the dependencies.

You weren't really meant to - lambdabot isn't exactly meant for anyone

half-maintained by me; I do easy fixes but nothing else since the
lambdabot codebase is large and IMO rotten.

Brainfuck and unlambda are separate executables, but they already have deps.
