[New-bugs-announce] [issue29846] ImportError: No module named _io

[Adam Stewart]

New submission from Adam Stewart:

I'm trying to build Python 2.7.13 with clang on macOS 10.12.3 with the Spack package manager, but it fails to build the _io module. The exact error message from the build log can be seen here:

https://github.com/LLNL/spack/issues/3478#issuecomment-287548431

This only seems to occur for me on macOS; I can't reproduce it on Linux. I checked my environment, but I don't have any Python-related environment variables, nor do I have any variables like DYLD_LIBRARY_PATH set that could cause problems. I'm a developer for the Spack package manager, so any problems that you help me solve will greatly benefit our community.

I have attached the build log. Please let me know if there is any more information I can provide you with.
