Prevent deprecation error messages from pkg_resources

Browse Source 
Currently pkg_resources is creating this warning message:

    RuntimeWarning: You have iterated over the result of
    pkg_resources.parse_version. This is a legacy behavior which is
    inconsistent with the new version class introduced in setuptools
    8.0.  In most cases, conversion to a tuple is unnecessary. For
    comparison of versions, sort the Version instances directly. If
    you have another use case requiring the tuple, please file a bug
    with the setuptools project describing that need.

Get the major_version directly from the version string passed in
instead so that the warning message is not raised.
