Possibly relevant is the stackage commentary on HP at http://www.stackage.org/install#why-not-haskell-platform:

• On Windows, it does not provide a complete environment (missing MSYS).
• By placing a large number of packages in the global package database, Haskell Platform installations are more easily corrupted.
• The choice of package versions conflicts with the needs of many commonly used packages.
• Some of the package versions included with the platform have known and severe bugs, and cannot be reliably upgraded.
