Error packaging Kivy with numpy library for Android using buildozer

I am trying to create an Android package of my Kivy application using buildozer but I am getting this error when I try to include the numpy:

resume of the error:

does anyone knows how to solve it?

P.S. I am using Ubuntu 14.04 64-bit
