Hi Mark,

Thanks once again for your excellent answer.

OK, I see that in show.cabal, ShowIO disappears from the exposed- 
modules section. This is confirmed by the fact that Show.hs has  
disappeared from the source. The contents of the latter were just a  
single instance declaration which now appears in ShowFun.hs.

 From all this I infer that lambdabot uses show, and in the process  
wants to import ShowIO: Such imports are indeed found in State/L.hs  
and State/Pristine.hs. Given that everything that used to live in  
ShowIO has been swallowed by ShowFun, we could just import ShowFun at  
those to place instead.

With you so far ..

is ~/.<packagename>/ some sort of cabal convention? Or are you using  
it as a shorthand for ~/.cabal/packages/<yaddayadda>/<packagename> ?  
Or is it some way in which you *could* organize your Cabal packages  
which happens to be different from what I have on my systems (by  

Ah, it is nothing to do with cabal, it's just lambdabot's personal  
data! (Which needs to have State/L.hs in it. It seems to work without  
Pristine.hs. Fine, at this stage I'm just prepared to accept this  
directory as magic).

I seem to have a working lambabot check. (i.e. 'lambdabot> check True'  
claims to pass 100 tests.)

Thank you.
