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

Traceback (most recent call last):
  File "setup.py", line 121, in <module>
    'build_ext': PySyckBuildExt,
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/distutils/core.py", line 125, in setup

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!

Attached code fails with:

MemoryError?

If a string contains a space followed by a single quote character, PyYaml?'s emitter fails to duplicate the single quote. The resulting YAML output yields a parse error:

>>> map = {'key': " 'single quoted text'"}
>>> yaml.dump(map)
"{key: ' 'single quoted text'''}\n"
>>> yaml.load(yaml.dump(map))
Traceback (most recent call last):

    ^

  in "<string>", line 1, column 10:
    {key: ' 'single quoted text'''}
             ^

If each single quote is preceded by a non-space character, then the error disappears:

>>> map = {"key": " foo'single quoted text'"}
>>> yaml.dump(map)
"{key: ' foo''single quoted text'''}\n"
>>> yaml.load(yaml.dump(map))
{'key': " foo'single quoted text'"}

The error seems to lie in the write_single_quoted function of module emitter.py. I've only encountered this problem with scalars represented in single quoted style.
