How to port a python package to a embedded system

[chenchao]

Hi, all:

     I have installed the PIP on my arm board now.  But the 'numpy' 
package includes some of C codes. This part of the C code must be 
x-compiled and I don't know how to x-compiled this package. So, is there 
a good idea for this issue?
