Build fails with Cython 0.14

[Philip S]

Hi,
I'm trying to build PyWavelets 0.2.0 under OS X with Cython 0.14
against 32-bit Python 2.6.6 from Python.org. The build fails; see the
output below. Downgrading to Cython 0.13 fixes the problem (I get a
successful build).

Googling on the error supports the notion that this results from a
change specific to Cython 0.14:

Here's my build log:

This issue was addressed in the repository version. Please grab the
code from https://bitbucket.org/nigma/pywt or https://github.com/nigma/pywt.
