piNes.c doesn't compile #22

WiringPi-Python $ sudo python setup.py install
...
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c WiringPi/wiringPi/piNes.c -o build/temp.linux-armv6l-2.7/WiringPi/wiringPi/piNes.o
WiringPi/wiringPi/piNes.c:25:22: fatal error: wiringPi.h: No such file or directory

Fixed by changing from #include <wiringPi.h> to #include "wiringPi.h" in my local copy, but this is bogus as it is in a separate project.
