On beta12, trying to compile Ethernet-examples-UdpNtpClient for teensy 3.0, I get

Code:
UdpNtpClient.cpp.o: In function `loop':
/home/linux/arduino-1.0.3/UdpNtpClient.ino:80: undefined reference to `makeWord(unsigned char, unsigned char)'
/home/linux/arduino-1.0.3/UdpNtpClient.ino:81: undefined reference to `makeWord(unsigned char, unsigned char)'
compiles OK if board is UNO
