* There now is full support for building Haskell packages as shared libraries
for GHC versions 7.4.2 or later. The Cabal builder recognizes the following
attributes:
- enableSharedLibraries configures Cabal to build of shared libraries in
addition to static ones. This option requires that all dependencies of
the package have been compiled for use in shared libraries, too.
- enableSharedExecutables configures Cabal to prefer shared libraries when
linking executables.
The default values for these attributes are arguments to the haskellPackages
expression.
* Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid plenty
of build and test suite errors. Without this setting, GHC seems unable to
deal with the UTF-8 character encoding that's generally considered standard
in the Haskell world.
* The Cabal builder supports a new attribute 'testTarget' to specify the exact
set of tests to be run during the check phase.
* The ghc-wrapper attribute ghcVersion has been removed. Instead, we use the
ghc.version attribute, which exists in unwrapped GHC derivations, too.
Any attempt to instantiate these expressions on an unsupported platform is
going to 'throw' an error. The call to 'assert' doesn't add any value to
that (and generates less readable error messages, too). Further details are
available at <https://github.com/NixOS/nix/issues/56>.
I have no idea whether that's going to work, and I can't test it for
lack of access to a MacOS X machine, but think chances are pretty good
that this is going to succeed.

The initial MacOS X binaries have been linked to libgmp.dylib using some
mad path in /opt that's now hard-coded into the program. Consequently,
$DYLD_LIBRARY_PATH must contain the place where libgmp really is for
those binaries to run correctly. Tested on i386-apple-darwin9.7.0.

Unfortunately, the same problem occurs again with 'installPackage', so as of
now, GHC cannot be installed on Red Hat.

suggestion. It's good to use an older GHC for bootstrapping because
old versions can build newer versions but not vice versa.
