example from  http://yaml.org/type/yaml.html fails to parse. Is it a wrong example ? (I have found already a few...)

>>> text = open('yaml.yaml').read()
>>> print text
# The following node should NOT be serialized this way.
encoded YAML node :
 !!yaml '!' : '!type'
 !!yaml '&' : 12
 !!value = : value
# The proper way to serialize the above node is as follows:
node : !type &12 value

>>> print yaml.load(text)

When I try to install pysyck on mac osx 10.5.5 by typing python setup. py install I get the following error:

I used to get another error, syck.h not found, then I made a file in my home folder thanks to xi:

I'd suggest you to create a file named .pydistutils.cfg in your home directory and add the following lines to it:

[build_ext]
include_dirs=/usr/local/include
library_dirs=/usr/local/lib

The Syck.h error disappeared, but I can't get the new one to go away, nor can I find solutions online.

I anybody has any idea, that would be great!
