[Python-modules-team] Bug#640940: python-numpy: numpy.distutils not multiarch aware

[Julian Taylor]

Package: python-numpy
Version: 1:1.5.1-2ubuntu2
Severity: normal
Tags: patch

numpy.distutils is not multiarch aware.
this causes problems when its searching for libraries.
E.g. when building in python-enable:

python setup.py develop
....
/usr/lib/pymodules/python2.6/numpy/distutils/system_info.py:459: UserWarning:
X11 libraries not found.
  warnings.warn(self.notfounderror.__doc__)

this is caused by numpy.distutils not checking in the multiarch triplet paths.
Attached patch fixes this issue, but due to the lack of a proper way to obtain
the triplet its quite ugly.
one could also use gcc -print-multiarch to obtain the triplet instead of dpkg-
architecture
