Comment:
Right, the patch doesn't build for me either, in either a GHC tree or as a
standalone package:
{{{
[ 7 of 21] Compiling Data.ByteString ( Data/ByteString.hs,
dist/build/Data/ByteString.o )
Data/ByteString.hs:488:23: Not in scope: `unsafeDupablePerformIO'

}}}
Duncan, could you take a look please?
