Yo también lo instalo sin problemas en win7 32bits, 64 bits y en linux
32/64bits.

Prueba haciendo (para distribuciones basadas en debian):
sudo apt-get install python3-dev (ahora no estoy con un linux
'debian-based' pero creo que es eso) y después, prueba a instalar de nuevo
numpy.

Otra opción sería usar conda. Creas un venv con conda y ahí podrás instalar
paquetes con conda y pip,....
