[SciPy-User] Error installing Scipy from repository with latest Cython installed

[Rishi Sharma]

I'm getting the same error while trying to build the epd numpy and scipy 
with cython0.16. The numpy build works smoothly, 

In [2]: numpy.__version__
Out[2]: '1.6.1'

but, the development version of scipy fails to compile,
(epd-7.3.2)bash-3.2$ python setup.py install
Cythonizing sources
Processing scipy/special/_ufuncs_cxx.pyx
....
Error compiling Cython file:
