Description:
After Upgrade of python2-m2crypto to Version 0.26.0-1 there is a missing dependency which prevents loading of the module.

Steps to reproduce:
~ $ python2
Python 2.7.13 (default, Jul 2 2017, 22:24:59)
[GCC 7.1.1 20170621] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import M2Crypto
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/M2Crypto/__init__.py", line 26, in <module>
from M2Crypto import (ASN1, AuthCookie, BIO, BN, DH, DSA, EVP, Engine, Err,
File "/usr/lib/python2.7/site-packages/M2Crypto/ASN1.py", line 15, in <module>
from M2Crypto import BIO, m2, util
File "/usr/lib/python2.7/site-packages/M2Crypto/BIO.py", line 10, in <module>
from M2Crypto import m2, util
File "/usr/lib/python2.7/site-packages/M2Crypto/util.py", line 20, in <module>
from typing import AnyStr, Tuple, Union # noqa
ImportError: No module named typing
>>>

So i have to install python2-typing and afterwards it works again:
pacman -S python2-typing
