Im still trying to get the hang of the PR workflow so my apologies in advance.

I closed the first PR by accident. I made the mistake of including a commit for another issue as well as the commit for this issue. When trying to clean up, I reverted back too far and Github closed the PR. I have submitted another PR that imports the lzma library as follows:

from test.support.import_helper import import_module

lzma = import_module('lzma')

Let me know if something still does not look right. I'll have some time this evening to work it out.
