Conflict with InterruptIn

I'm building a puck-based program and would like to update a GATT characteristic when one of the built in nRF51822 buttons is pressed. But if I instantiate a InterruptIn as so:

InterruptIn button(BUTTON1);

I get a compiler error

Error: Symbol GPIOTE_IRQHandler multiply defined (by gpio_irq_api.o and app_gpiote.c.NRF51822.o).

What's the best way to do this with a puck project? I'm currently thinking of resorting to a Ticker, which seems like it can't be the best way....

I got it working! I used PinDetect: http://mbed.org/users/AjK/code/PinDetect/docs/cb3afc45028b/classAjK_1_1PinDetect.html
