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?

Hi Jacek and Gwern,
In the upgrade from mueval from 0.8 to 0.8.1, some of the mueval command line options were changed:
--loadfile => --load-file --noimports => --no-imports
For Plugins/Check.hs I change --loadfile to -l.
To convince lambdabot to run on gentoo, I patch it to use --no- imports to avoid this problem:
% mueval -e '1 + 2' Ambiguous module name `Control.Monad.Cont': it was found in multiple packages: monads-fd-0.1.0.2 mtl-2.0.1.0 monads-tf-0.1.0.0 %
And I patch the lambdabot /usr/share/lambdabot-4.2.3.2/ghc-7.0.3/ State/L.hs to used -XPackageImports. Then mueval works:
% mueval --no-imports -l ~/.lambdabot/State/L.hs -e '1 + 2' 3 %
And lambdabot works:
% lambdabot Initialising plugins ................................................... done. lambdabot> @check True +++ OK, passed 100 tests. "OK, passed 100 tests." lambdabot>
