New issue 2655: Pypy + Aubio 3 or 4 numpy bugs
https://bitbucket.org/pypy/pypy/issues/2655/pypy-aubio-3-or-4-numpy-bugs

Stuart Axon:

I've been testing PyPy nightly and aubio, and quite a bit seems to work.

There are some numpy tests that don't pass in test_cvec.py - it looks like there are only about 3 or 4 actual errors.


In my virtualenv I had to set ```LD_LIBRARY_PATH=$(python-config --prefix)/lib```
 
After I had built and aubio I ran the python tests:

```
$ cd aubio/python/tests
$ ./run_all_tests
