uses for its core libraries, so that these files integrate seamlessly into one
profile, living right next to each other. This change is eventually going to
simply our with-packages wrapper quite a bit.
When the ghc-paths library is compiled, the paths of the
compiler it is compiled with are being hardcoded in the
library (and can then be queried from other applications
using the library).
But on Nix, packages are compiled with ghc-wrapper, and
subsequently possibly used with a special version of ghc
generated for a particular environment of packages. So
one version of ghc-paths may potentially end up being
used by lots of different instances of ghc. The hardcoding
approach fails.
As a work-around, we now patch ghc-paths so that it allows
setting the paths that can be queried via environment
variables. Specific GHC environments can then set these
environment variables in the wrapper shell script that
invokes GHC.
This should at least partially solve issue #213.
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 got the following error in 4 consecutive attempts:

This change allows use of the with-packages wrapper in user profiles that are
being updated with "nix-env -u \*". The previous name this expression generated
was considered by Nix to be an older version of "ghc-7.0.4-wrapper", because
that name has a higher priority.

Merge conflicts:
* unzip (almost trivial)
* dvswitch (trivial)
* gmp (copied result of `git merge`)
The last item introduced gmp-5.0.3, thus full rebuild.
+ensureDir->mkdir -p in TeX packages was catched by git but not svn.

I assumed that Hydra would arrive at that result anyway, but apparently
it doesn't: no x86_64-darwin builds have occurred despite the fact that
we can bootstrap on that architecture now.
