WConstants.h: No such file or directory

a local group of student trying build arduino lc meter (http://forum.arduino.cc/index.php?topic=8437.0) came me under mistaken impression arduino expert. blink runs fine trying compile attached program under 1.5.8 1.6.3 following message:

lcfrequencymeter.pde:13:24: fatal error: wconstants.h: no such file or directory

compilation terminated.

error compiling.

maybe due peculiar flavor running under "netbeans" or arduino team switching things again. suggestions?

change lines #include <wconstants.h> #include <arduino.h>
