New description:

 Google appengine standard environment (Google cloud SDK) uses a sandbox
 that prohibits the use of _ctype. pycryptodome uses _ctype, which fails to
 import in the cloud sdk sandbox "ImportError: No module named _ctypes".
 This was really hard to diagnose correctly.

 This incompatibility should be documented in the package descriptions of
 both ports, as pycryptodome is not a 100% replacement for pycrypto.

 WORKAROUND: download and manually build pycrypto-2.6.1
