The password is "haskell'" (note the final apostrophe). Isaac: maybe we should use a simpler password?
The bug is that "runhaskell Setup.hs --enable-library-profiling" doesn't imply -auto-all with ghc, so the profiled library contains only manual cost centres - in other words, it never shows up in profile output.
Not adding -auto-all is the right default; the intended usage is for building a profiled version of the library so that a user can profile their own application against it, not to profile the library itself.
If you want to profile the library, add "ghc-options: -auto-all" to the .cabal file. When we have configurations you'll be able to make this optional, but for now just add it by hand to .cabal (and don't forget to remove it later).
Should -auto-all be used for --enable-executable-profiling though? I think its missing there too, which seems wrong? -- Don
