New issue 2994: multiarray import fails - Symbol not found: _aheapsort_bool on macOS
https://bitbucket.org/pypy/pypy/issues/2994/multiarray-import-fails-symbol-not-found

S. Moon:

macOS Version: 10.13.6
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin17.7.0

(numpy package was installed through pip, and not built from source)

Steps to repro:
1. Install numpy on a fresh pypy3.5 / 3.6 installation (Affects at least version PyPy3.6 v7.1.0-beta and PyPy3.5 v7.0.0, and also the latest 3.6 nightly - pypy-c-jit-96343-de061d87e39c-osx64)
2. `import numpy`

Logs:

This does not repro on Linux builds of the same pypy versions.
