Haskell 2010 doesn't like the additional level of indentation after the  
"let log" line.

2) Can this code be formatted in a way to make Haskell 2010 happy?
The lines after the let must be indented more:

main :: IO ()
main = do
     gen <- getStdGen
     let log = runModel gen $ do
           initialize 72
           report
           replicateM_ 50 $ do
               replicateM_251 migrate
               report
     putStr . format $ log
