py27-numpy fails to compile with standard compiler on 10.5

[rmottola (Riccardo)]

Package py27-numpy (1.15.1) fails to compile on Leopard 10.5 with the error below. I suppose not finding immintrin.h causes the issue.

C compiler: /usr/bin/gcc-4.2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -arch i386

When built with clang 3.9 from macports, that is, port -v upgrade py27-numpy configure.compiler=macports-clang-3.9

compiles and installs fine.
