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

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:
