The failures take place in packages that are not part of core Python.

It seems that dateutil attempts to import "_thread" from six.moves
where it is not defined.

So the problem exists - apparently - between dateutil and six.  You
might be able to install different versions of the packages and make
it work that way, but if the dependencies of non-ASE packages are not
handled automatically, this could become quite a mess.
