Same problem here with matplotlib-2.2.2-r1 and numpy-1.14.5
Notice File "/usr/lib64/python2.7/site-packages/numpy/lib/__init__.py", line 18, in <module> from . import scimath as emath the "from ." means that it is a relative import from the same folder as the parent caller. Therefore it tries to import scimath.py (or an alias for it) in /usr/lib64/python2.7/site-packages/numpy/lib/ and sure enough I have a file of that name in that directory. Do you?
Hum, do you have dev-python/future installed (and I mean future not futures)? This should be a dependency of numpy but isn't. Note that numpy upstream does a poor job of signalling that it is needed. But the first line of /usr/lib64/python2.7/site-packages/numpy/lib/__init__.py is from __future__ import .... which is a signal you need future installed.

Thanks for the hint, installing dev-python/future fixed this problem for me. So this definitely should be added as a dependency. Unfortunately, matplotlib still fails to build, now with another error message: UPDATING /var/tmp/portage/dev-python/matplotlib-2.2.2-r1/work/matplotlib-2.2.2-python3_6/build/lib/matplotlib/_version.py set /var/tmp/portage/dev-python/matplotlib-2.2.2-r1/work/matplotlib-2.2.2-python3_6/build/lib/matplotlib/_version.py to '2.2.2' running build_ext Traceback (most recent call last): File "setup.py", line 277, in <module> **extra_args File "/usr/lib64/python3.6/site-packages/setuptools/__init__.py", line 143, in setup return distutils.core.setup(**attrs) File "/usr/lib64/python3.6/distutils/core.py", line 148, in setup dist.run_commands() File "/usr/lib64/python3.6/distutils/dist.py", line 955, in run_commands self.run_command(cmd) File "/usr/lib64/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "/usr/lib64/python3.6/distutils/command/build.py", line 135, in run self.run_command(cmd_name) File "/usr/lib64/python3.6/distutils/cmd.py", line 313, in run_command self.distribution.run_command(command) File "/usr/lib64/python3.6/distutils/dist.py", line 974, in run_command cmd_obj.run() File "setup.py", line 128, in run return BuildExtCommand.run(self) File "/usr/lib64/python3.6/site-packages/setuptools/command/build_ext.py", line 78, in run _build_ext.run(self) File "/usr/lib64/python3.6/site-packages/Cython/Distutils/old_build_ext.py", line 185, in run _build_ext.build_ext.run(self) File "/usr/lib64/python3.6/distutils/command/build_ext.py", line 339, in run self.build_extensions() File "/usr/lib64/python3.6/site-packages/Cython/Distutils/old_build_ext.py", line 192, in build_extensions ext.sources = self.cython_sources(ext.sources, ext) File "/usr/lib64/python3.6/site-packages/Cython/Distutils/old_build_ext.py", line 263, in cython_sources extension.include_dirs = list(extension.include_dirs) File "/var/tmp/portage/dev-python/matplotlib-2.2.2-r1/work/matplotlib-2.2.2-python3_6/setupext.py", line 921, in __get__ result = obj._hooks[self._name]() + result File "/var/tmp/portage/dev-python/matplotlib-2.2.2-r1/work/matplotlib-2.2.2-python3_6/setupext.py", line 941, in include_dirs_hook import numpy File "/usr/lib64/python3.6/site-packages/numpy/__init__.py", line 142, in <module> from . import add_newdocs File "/usr/lib64/python3.6/site-packages/numpy/add_newdocs.py", line 13, in <module> from numpy.lib import add_newdoc File "/usr/lib64/python3.6/site-packages/numpy/lib/__init__.py", line 19, in <module> from .polynomial import * File "/usr/lib64/python3.6/site-packages/numpy/lib/polynomial.py", line 13, in <module> import numpy.core.numeric as NX AttributeError: module 'numpy' has no attribute 'core'
I'd like you to rename this bug so what's missing is clear and can be acted upon. For the matplotlib build bug please open another bug and I will have a look at that too.
