Doesn't compile with integer-simple...
Industrial Haskell Users Group seemed interested in version of GHC built with only integer-simple. Currently all Haskell Platform packages compile in this setup, except for text. I upgraded dependency to a version of text that may build with integer-simple by setting appropriate flag, but automatic detection would probably need a new configure or a new Cabal feature.
I'm not sure what in the platform could change to help this situation. It seems to me like changes would be needed to both the text package, and cabal to handle this automatically.
I suppose another approach would be to produce patches to text to have a configuration flag for building with integer-simple, and then a patch to haskell-platform to have some sort of configuration option.
Current version of text package already includes "integer-simple" flag. It is just a matter of forwarding that flag from haskell-platform.
