Yes, that isn't a "supported" workflow.  The rule is that we support building 
GHC using either:

   (a) any released version of GHC version 5.04 and later, or
   (b) itself.

(by "itself" we mean a compiler built from these same sources).

In other words, building the HEAD using a 6.5 snapshot isn't guaranteed to work. 
  It might work.
