0.6.3 cannot import name Outcome on py24/25

[Oyster]

it is so strange, I have installed py lib 0.9.2, but
[code]
>>> from py.__.test.outcome import *
>>> dir()
['EXIT_INTERNALERROR', 'EXIT_INTERRUPTED', 'EXIT_NOHOSTS', 'EXIT_OK',
'EXIT_TESTSFAILED', 'ExceptionFailure', 'Exit', 'Failed',
'OutcomeException', 'Passed', 'Skipped', '__builtins__', '__doc__',
'__name__', 'deprecated_call', 'exit', 'fail
', 'importorskip', 'py', 'raises', 'skip', 'sys']
[/code]
you can find the is no Outcome

so I changed sympy\utilities\pytest.py
[code]
from pytest import raises
[/code]
to
[code]
#from pytest import raises
[/code]

else

[code]
>>> from sympy import Symbol, cos

With py.test 0.9.1-3:

In [1]: from py.__.test.outcome import Outcome

In [2]: Outcome
Out[2]: <class py.__.test.outcome.Outcome at 0xb76f9b9c>

So they changed the interface and it breaks sympy. In
sympy/utilities/py.test we have:

try:
import py
disabled = False
except ImportError:
disabled = True

So normally it is disabled and not used if the py.test is not
installed. Thanks for noticing this, it is a bug and the fix is to
move all the imports into the "try" clause above.

Hi Oyster,

could you please try our latest git versino? You can download a zip file here:

http://git.sympy.org/?p=sympy.git;a=snapshot;h=HEAD;sf=zip

It should be fixed.
