libyaml is not found or a compiler error

[natea]

When I tried to install cookiecutter, I got the following error:

  Running setup.py install for PyYAML
    checking if libyaml is compilable
    clang -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -I/usr/local/opt/sqlite/include -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c build/temp.macosx-10.9-x86_64-2.7/check_libyaml.c -o build/temp.macosx-10.9-x86_64-2.7/check_libyaml.o

    libyaml is not found or a compiler error: forcing --without-libyaml
    (if libyaml is installed correctly, you may need to
     specify the option --include-dirs or uncomment and
     modify the parameter include_dirs in setup.cfg)

I don't know if libyaml is required in order for cookiecutter to work properly, but if so, then the output is misleading since the "Successfully installed PyYAML" message implies that it was installed correctly.

I was able to avoid this error by installing libyaml using Homebrew:

$ brew install libyaml

I think PyYAML will fall back to a pure-python parser if libyaml is not available, so even when it said it failed, everything is cool.

On a related note: if someone has to use yaml for part of the functionality (in this case, for .cookiecutterrc) it seems like they should get to use it wherever.

Here's my hack of cookiecutter that does just that:
