I am trying to install the sparsesvd library on my PythonXY but I encounter some problems. My environment is a Windows 7, I have installed PythonXY 2.7.3.1 and mingw32 (gcc vand g++ ver. 4.7.2). I edited distutils.cygwinccompiler removing all "-mno-cygwin" and have a distutils.cfg where I specify the compiler is mingw32.
Yet, when I run from shell easy_install sparsesvd I get back:

the same problem appears with the command pip install sparsesvd.
What could be the problem?
read the last line of the error..
Parent module 'numpy.distutils' not found
you have to install numpy first.
