Hi, I'm getting an error when compiling the project files for the LED array kit:

pi@raspberrypi ~/nerdkit/Code/ledarray_test $ make
make -C ../libnerdkits
make[1]: Entering directory `/home/pi/nerdkit/Code/libnerdkits'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/home/pi/nerdkit/Code/libnerdkits'

ledarray.c:94:8: error: attempt to use poisoned "SIG_OVERFLOW0"
ledarray.c: In function ‘SIG_OVERFLOW0’:
ledarray.c:94:1: warning: ‘SIG_OVERFLOW0’ appears to be a misspelled signal handler [enabled by default]
make: *** [ledarray.hex] Error 1

I'm using a Raspberry Pi - all the other demo code (e.g. the temp sensor) compiles with no problems at all - other than a minor step which i've detailed here http://kimondo.co.uk/nerdkit-with-the-raspberry-pi

any ideas?

The ISR routine needs changed to the current method of interrupt routines. The SIG_OVERFLOW is being phased out see THIS page for details.
