These errors are caused because the function set_irq_type and
IRQ_TYPE_RISING_EDGE are no longer supported under the recent kernels.

You should take a look at a newer version of gpio-event.

You'll notice that there are a bunch of different tarballs on this page:
<http://docswiki.gumstix.com/GPIO_event>

If you look at the differences between each one, you'll see some of
the changes required for each specific kernel version.
