Comment:

 The bug of the confusing panic message has been fixed, somewhere between
 version 7.6.3 and version 7.8.3. Repeating the steps from comment:5, or
 just `ghci -ignore-package base`, now prints:

 {{{
 GHCi, version 7.8.3: http://www.haskell.org/ghc/  :? for help

 Top level:
     Failed to load interface for ‘Prelude’
     Use -v to see a list of the files searched for.
 }}}

 @irneb. I'm sorry you ran into this problem. I understand you tried
 solving the problem by installing libffi from looking at #3144, but that
 is a 6 year ticket.

 For anyone else running into problems like this: try installng the most
 recent version of GHC first, and start over with new `.ghc` and `.cabal`
 directories in your home directory. Also make sure there is no strange
 GHC_PACKAGE_PATH variable in your shell environment (maybe from a previous
 installation).
