py27-numpy fails to compile with standard compiler on 10.5 due to: immintrin.h: No such file or directory

[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.

Error: Failed to build py27-numpy: command execution failed

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.
