How to create a hard link from within a Python script on a Mac?

I'm assuming with a call to a UNIX shell, but I was wondering if there are other options from within Python.

My guess would also be that it is a permission problem. For me (OS X 10.7.3), this works:

$ ls
slask.py  system.py  system1.gif  system2.gif

$ python
>>> from os import *
>>> link('system2.gif', 'mylink.gif')
>>> exit()

$ ls
mylink.gif  slask.py  system.py  system1.gif  system2.gif

And just to make it clear, "Hard links may not normally refer to directories and may not span file systems."

This is because hard linking a directory could create an infinite loop. So directories need to be created using os.mkdir. Then files can be hard linked into that new directory.

os.link claims to work on all Unix platforms. Are there any OS X specific issues with it?
