    Priority:  normal       |   Milestone:  6.8    
   Component:  Compiler     |     Version:  6.7

  Difficulty:  Easy (1 hr)  |    Testcase:         
Architecture:  Unknown      |          Os:  Unknown
----------------------------+-----------------------------------------------
The version in an interface file is currently being checked too late,
 which means that GHC gets confused by out of date `.hi` files instead of
 emitting a proper error message.  (bug isn't in 6.6, only HEAD).
