[Haskell-cafe] yi + cabal-dev

I'm trying to run yi. More precisely, I'm trying to run yi in its own sandbox, created by cabal-dev. yi uses dyre to recompile its config file. Unsurprisingly, this fails, since ghc doesn't know anything about the yi install unless pointed to a separate package database. Has anyone gotten a similar setup to work, or does anyone have any suggestions? -- Alex R
