I have a PyQt5 application running on Windows that I'd like to get running
on CentOS 6 as well. I'd prefer to install from wheels rather than source,
as described in Installing PyQt5
<http://pyqt.sourceforge.net/Docs/PyQt5/installation.html> . When I do so,
and attempt to run, I get this error:

ImportError: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by
> /home/jsnoaa/pyqt5-framdata/virtualenv/centos_pyqt5_framdata/lib/python3.6/site-packages/PyQt5/QtCore.so)

My read of the error: QtCore.so is expecting a /lib64/libc-2.14.so or
later, but /lib64/libc.so.6 on CentOS 6.9 is linked to /lib64/libc-2.12.so.


   - CentOS release 6.9 (Final) (2.6.32-696.6.3.el6.x86_64)
   - Python 3.6.1 (wget
   - PyQt5 5.9 (pip3.6 PyQt5==5.9)

I read with interest How to Install Qt 5 and Qwt on CentOS 6
<http://wiki.qt.io/How_to_Install_Qt_5_and_Qwt_on_CentOS_6>. Is this note
saying that one must install PyQt5 onto CentOS 6 by compilation, not from
