Copy only the pc files related to X11 and OpenGL.
This should allow us to build our own version of libraries like
cairo without having the native ones be accidentally dynamically
linked in to things that depend on them.
Before this patch if we `dyldinfo -dylibs libpangocairo` we can
see that it was dynamically linked against the OS X (but seemingly
built against include files from the nix one, as we would get a
runtime complaint about missing symbols)
Setfile is included by other derivation, which in turns makes them unfree, too.
This causes plenty of evaluation errors on Hydra, i.e.:
at `haskellPackages_ghc763_profiling.wx.x86_64-darwin' [nixpkgs = ..., officialRelease = false]:
user-thrown exception: package ‘setfile’ has an unfree license, refusing to evaluate
Now, it's true that "setfile" is unfree, but this doesn't affect us: our
derivation doesn't include the actual binary -- it just contains a symlink to
"/usr/bin/SetFile". Arguably, our setfile derivation is free and we can
re-distribute it.
* Dropped "nolongdouble.patch". The patch no longer applies to Python 2.6, and
apparently isn't required anymore either.
* Added access to native Darwin arch utility. Python tries to run 'arch' in
the configure stage, but that binary reside in /usr/bin. To make it
available to the expression, the small wrapper darwinArchUtility is added as
a buildInput if appropriate.
* Don't pass --enable-shared. The build fails if we try to enable building of
shared libraries, apparently because some required libraries aren't linked,
i.e. the linker call isn't right.
TODO:
* Figure out how to enable shared linking.
* The resulting binary on Darwin seem to lack the binascii module.
