[Haskell-cafe] "hiddenness"

[Vasili I. Galchin]

Hello,

     When I am compiling a module, I get "Could not find module
'Control.Module.State':
                                                                  it is a
member of package mtl-1.1.0.2, which is hidden"

     1) What is the efficacy of "hiddenness"?

     2) I have forgotten what tool I run to expose a package. ??

     3) In another vein, the code is using Data.Finitemap ... so I guess I
must "darcs" install this?

Regards,

Vasili
