Created attachment 352136 [details, diff] Patch to pytables-3.0.0.ebuild to make it pass PYTHON_USEDEP to appropriate dependencies The dev-python/pytables-3.0.0 ebuild uses the new Python EAPI=5 system to determine which versions of Python it will build for. Specifically, due to its PYTHON_COMPAT value, it has the following values added to its USE flags: python_targets_python2_5, python_targets_python2_6, python_targets_python2_7, python_targets_python3_2, and python_targets_python3_3. One of pytable's dependencies is dev-python/numexpr, which (in version 2.1, which is the only version currently in portage) also uses the EAPI=5 system for Python versions. However, pytables does not require that numexpr be built for the same versions -- even though, if numexpr lacks a version that pytables requires, pytables will fail to build. To correct this, pytables should specifically depend on the same versions it itself has. The attached .ebuild patch resolves this issue, as well as fixing the dependency on numpy as well (which exhibits the same problem, although I didn't test this to verify that pytables breaks if numpy lacks a required Python version). TL;DR: pytables-3.0.0 does not pass its PYTHON_COMPAT/PYTHON_USEDEP variable to its dependencies; the attached patch fixes this problem.
