[Haskell-cafe] lambdabot check

[Jacek Generowicz]

Hi Mark,

Thanks for your wonderfully lucid, concise and complete explanation of  
the problem and its solution (included below).

When I apply your patch and reinstall lambabot, I now get the  
following problem:

lambdabot> check True
   Could not find module `ShowIO`:
    It is a member of the hidden package `show-0.3.4`.
    Use -v to see a list of the files searched for.

I recognize the message about -v as a ghci one. How could I inject  
this -v into lambabot ?

I get the same error on both of the machines on which I am trying  
this. On one of them I already have show-0.3.4 and show-0.4.1.1, on  
the other I have only show-0.4.1.1.

Any suggestions?
