Just to test whether the testing tools were working correctly on my
machine, I tried running the test cases under 'sympy/core' for sympy
version 0.6.2. This failed. The reulsts are shown at the end of the
post.
One error claimed that the 'Singleton' class could not be imported
from 'sympy.core.basic'. I looked in the basic module and was not able
to locate a Singleton class. I have not looked at the other errors in
detail yet. I am assuming that sympy 0.6.2 passed all the tests before
it was released, so I am not sure why the test are failing for me.
Anyone have any insights? (I think my paths are set up correctly, but
I don't know of a good way to tell the path a module was loaded from
just to check. How do you do this?)
