python3-minimal (3.4.3-4) fails configuration under Hercules

[Stephen Powell <zlinuxman@wowway.com>]

Here's a "heads up" for those of you who are running Debian under Hercules.

I recently did an "apt-get upgrade" for my stretch (testing) system under
Hercules, and it failed configuration with this error:

-----

Setting up python3-minimal (3.4.3-4) ...
Traceback (most recent call last):
  File "/usr/bin/py3compile", line 34, in <module>
    from debpython.version import SUPPORTED, debsorted, vrepr, \

    microseconds=999999)

dpkg: error processing package python3-minimal (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 python3-minimal
E: Sub-process /usr/bin/dpkg returned an error code (1)

I spent the weekend trying to resolve this.  The bottom line: there is a
bug in Hercules itself.  The version of Hercules currently packaged for
Debian, 3.07, has a bug in the emulation of the s390x hardware which
causes configuration of the above package to fail.  I downloaded Hercules
3.11 directly from upstream, compiled it from source, and installed it.
The above error disappears under Hercules 3.11.  The bottom line:

   We really need a new hercules package for Debian!
