This package is building against numpy 1.9.3

I just noticed that this package is building against numpy 1.9.3 instead of the conda_build_config.yaml value set (1.13.1). See here:

https://gitlab.idiap.ch/bob/bob.bio.vein/-/jobs/124089

This happens despite the fact we pin the value of numpy correctly in the host section with numpy {{ numpy }}. Are we missing something here?

@amohammadi: for this reason, I cannot make my install-build-deps script run! What is the purpose of conda_build_config.yaml if that is not correctly enforced?
