When trying to run yi, it fails to compile main, and exits with an error

[guest]

I am using ghc-6.6.1 installed in a non-standard location, and I just built yi-0.2 also for a non-standard location, and the first time I run it I get:

<interactive>:1:33:
    Failed to load interface for `Yi':
      Use -v to see a list of the files searched for.
yi: panic! (the 'impossible' happened)
  (GHC version 6.6.1 for i386-unknown-linux):
        Could not compile Yi.main!

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

The output from the configuration and build is:

Let me know if there is any more info I can provide.

Has anyone either reproduced this or failed to reproduce it?

Does anyone know if it's expected to work?

I have a similar setup and a similar problem. It manifests itself slightly differently. I have a gentoo system with my own ebuilds for ghc-6.6.1 (simply renaming the 6.6 ebuild from the haskell overlay) and cabal-1.1.6.2 (likewise). When I try to install yi (using the 0.2 ebuild from the overlay) everything goes (apparently) fine until the linking stage when the following output ensues:

Getting the darcs version and making with "make emacs" ends the same way. Is this the same issue?

These are absolutely NOT bugs in GHC. Please report to the Yi people instead:
