Without this patch buildout will copy eggs from the nix store into the
./eggs directory and then try to compile them. This fails because they
are read only. This patch changes the behaviour to create symlinks to
eggs available in the nix store instead of copying them, and not to
try to compile the eggs in the store. To differentiate this from the
default buildout (which may be provided otherwise e.g. as a
dependency) the executable is renamed to buildout-nix.
This can be used in conjuntion with myEnvFun to create development
environments which make use of the python modules available in the
store while downloading any additional required eggs. A pleasant side
effect is that you can conveniently replace the symlink with a copy
for debugging purposes.
Thanks to @phreedom for reporting the broken URL used fetchgit, which
was because I deleted my fork repository. Fortunately, in the meantime
other forks got to a more "working" state and being more actively
maintained than my fork. So that's why I switched using @nemerle's fork
now, as it is the the most usable one out there, at least in our case.
One stupid thing I've done in the first place was to use "1.0pre" as the
version and the fork uses "alpha 0.3.2", so it essentially is some kind
of a "downgrade" if you just look at the version.
Fortunately, peer-unreviewed research based on guesswork has shown that
I'm the only one using Boomerang on NixOS, so this shouldn't have a big
impact on the other non-existent users.
Also, this drops dependencies on boehmgc and cppunit, because building
with either one or both will fail at the moment.

Also leaving 0_8 branch, as it's compatible with older ffmpeg versions.
I'm planning that all expressions will be able to switch easily
between ffmpeg and libav (whatever default we choose, but I prefer libav).
Edited (twice) according to notes on the reverted b003138.
Building of haddock for packages with UTF-8 source is already
fixed in the stdenv-updates branch. This fixes modular-arithmetic
until that branch is merged. Will send another pull request to
add back haddock for that branch.
