[Haskell-cafe] building hare on ghc-6.6

[Yang]

how do i build hare on ghc-6.6? after removing all references to
package lang from myghc--make, i get:

RefacUtils.hs:54:5: parse error on input `HasModName'

this just seems like a normal class being exported.

the makefile proceeds past this to build a bunch of other files fine.
if i ignore this and try loading the emacs file and entering
haskell-refac-mode on a .hs buffer i get:

Can't exec program: /home/yang/tmp/pkg/pure/todo/HaRe_20012006/refactorer/pfe
