Is it too late to use the "new" [staging] repository instead of
[testing] for this ? It was aimed at large rebuilds, and it looks it
is the case here. Many incompatibilities are expected: if GHC7 is
supposed to enter the main repositories in 2011, [testing] may be too
early.

For example, the current version of mtl cannot be built with GHC7, but
mtl-1.1.1.0 is compatible. I see that HP2011 may set mtl2 to be the
standard, so we have the choice of either:
* follow haskell-platform ML and choose to build the proposed contents
of HP2011 in a test repo
* keep HP2010 versions of the libraries unless they are incompatible
with GHC7, and then do the minimal upgrade so that most packages
remain compatible.
