I did try that; after adding a bunch of packages to the .cabal file and trying to build i get this: [ 1 of 81] Compiling Plugin.Dict.DictLookup ( Plugin/Dict/DictLookup.hs, dist/build/lambdabot/lambdabot-tmp/Plugin/Dict/DictLookup.o )
Plugin/Dict/DictLookup.hs:33:4: Ambiguous type variable `e' in the constraint: `GHC.Exception.Exception e' arising from a use of `handle' at Plugin/Dict/DictLookup.hs:33:4-42 Probable fix: add a type signature that fixes these type variable(s) cabal: Error: some packages failed to install: lambdabot-4.2.2.1 failed during the building phase.
