I can't reproduce this with the i386/Linux 6.8.0.20070925 and
./Setup configure; ./Setup build:

[...]
[28 of 53] Compiling Data.Tree.AVL.Join (
Data.Tree.AVL/Data/Tree/AVL/Join.hs, dist/build/Data/Tree/AVL/Join.o )
[29 of 53] Compiling Data.Tree.AVL.Test.Utils (
Data.Tree.AVL/Data/Tree/AVL/Test/Utils.hs,
dist/build/Data/Tree/AVL/Test/Utils.o )
[...]
[38 of 53] Compiling Data.Collections ( Data/Collections.hs, dist/build/Data/Collections.o )

Data/Collections.hs:758:33:
    Couldn't match expected type `(k, a)'
           against inferred type `Map.Map k (Map.Map k a)'
      Expected type: m (Map.Map k a, (k, a))
      Inferred type: m (Map.Map k a, Map.Map k (Map.Map k a))
    In the second argument of `ap', namely `Map.minView x'
    In the expression: return swap `ap` Map.minView x


If you think it's still broken, please let me know.


Thanks
