Small safety hint for distributors: the haskell-platform.cabal file mandates network == 2.3.1.0 and HTTP == 4000.2.5, but the latter by default depends on network >= 2.4 && < 2.5. So if you want to avoid to include the same package in different versions (which at least OpenBSD does), you'll have to configure HTTP with -fnetwork23 (which changes the dependency to network < 2.4).
I think HTTP can solve this in a better way, instead of using #ifdef NETWORK23 uriDefaultTo a b = maybe a id (a `relativeTo` b) #else uriDefaultTo a b = a `relativeTo` b #endif it could use #ifdef MIN_VERSION_network(2,4,0) uriDefaultTo a b = a `relativeTo` b #else uriDefaultTo a b = maybe a id (a `relativeTo` b) #endif That way it will compile on both old and new network versions without any user interventions (including cabal flag). -- Johan
