Installing `numpy` within a virtualenv in Ubuntu 11.10

Question

I got the following exceptions when install numpy using easy_install numpy, could somebody help please? Whether I am using pip or easy_install, I got the same problems. It is hard to understand what's going wrong.

Answer 1

Perhaps the GCC is not updated. I just did a apt-get upgrade gcc and numpy compiled successfully.
