      Arrrgh,

now I get to:
[ 4 of 78] Compiling Lib.Parser       ( Lib/Parser.hs, 
dist/build/lambdabot/lambdabot-tmp/Lib/Parser.o )

Lib/Parser.hs:7920:4: Not in scope: `as_name'

Lib/Parser.hs:7926:4: Not in scope: `qualified_name'

Lib/Parser.hs:7932:4: Not in scope: `hiding_name'

Lib/Parser.hs:8015:4: Not in scope: `minus_name'

Lib/Parser.hs:8021:4: Not in scope: `pling_name'

Lib/Parser.hs:8034:4: Not in scope: `pling_name'

what's happened here?
How do I fix that?

You need to list it in the "build-depends" field in the .cabal file.
Is it possible for cabal to catch this mistake and report a different
error?  I've bumped into it before as well and found the error message
to be enough misleading that I went down the wrong trouble shooting
path.  Maybe GHC should give a better diagnostic here?

Yes, very misleading.

Cheers,
