Hi there

I'm new to Haskell and need some help to get started faster (busy busy busy).
I like to adjust and extend an editor to my liking and I choose Yi.

Only installation with 'cabal install yi' in a Cygwin shell under MS Windows XP ended in:
Yi\Prelude.hs:182:9:
    Duplicate instance declarations:
      instance Category Accessor.T -- Defined at Yi\Prelude.hs:182:9-38
      instance Category Accessor.T
        -- Defined in data-accessor-0.2.1:Data.Accessor.Private
cabal.exe: Error: some packages failed to install:
yi-0.6.1 failed during the building phase. The exception was:
exit: ExitFailure 1

:(

Seems easy to fix but I can't even find where on my drive I can find the source code.

Where is the source?

Cheers,
Jaco
