"base" isn't listed among the build-depends of the executable, so the obvious thing is to add base to the build-depends and see what happens then (might also be necessary for some other packages). I'm not sure whether iterating that strategy will get lambdabot to build or it's too bit-rotted, so prepare to dive into the sources if you really want it to build.

"unix" appears to be in the build-depends of the "Library", but not in the build-depends of "Executable lambdabot" Adding "unix" to the second build-depends appears to fix the error (but now it complains that base is hidden).

Main.hs:11:7: Could not find module `System.Posix.Signals': It is a member of the hidden package `unix-2.4.0.0'. Perhaps you need to add `unix' to the build-depends in your .cabal file.

Interesting, because unix _is_ listed in build-depends in the .cabal file for lambdabot.

Does "ghc-pkg check" complain about unix? Does "ghc-pkg list unix" say it's there?

I have a feeling this has something to do with the interaction between

Highly unlikely unless there's an inconsistency in the packages on your system.
