I don't understand why you are seeing that problem *unless" you might be 
running into this issue that I found by searching for "sincos Android":

https://code.google.com/p/android/issues/detail?id=38423

That looks awfully suspicious.  If it isn't that, I don't know what to 
tell you.  You could open an issue on the Python bug tracker 
(bugs.python.org) but we don't officially support Android so I doubt 
that will help much.  If you haven't already, you might try asking on 
some Android forums; I know other oddities of building things on Android 
have been reported.

Good luck!
