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,

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!

I dont understand how PyYAML reads YML files with "Block Mapping", (I call these "Nested variables" in my example):

>>> document = """
 Variable 1:
   x: a
   y: b
   z: c
 Variable 2:
   1: a
   2: b
   3: c
 """
>>> yml=yaml.load(document)
>>> yml.keys()
['Variable 2', 'Variable 1']

>>> yml["Variable 1"].keys()
 ['y', 'x', 'z']

So it looks like PyYAML loads the document in reverse order, "Variable 2" is read before "Variable 1". That's fine. But why is ymlVariable 1?.keys() in a random order? It seems like it should either be chronological (x,y,z) or reverse chronological (z,y,x).

I'm having a hard time parsing tickets #29 and #116, which might be related... Can you offer up some insight?

PS: Sorry if this is the wrong place for a question... I couldn't find a mailing list.
