On Debian Wheezy this won't work. I applied your patch
http://p.sipsolutions.net/b02ac4b02793dfcf.txt and now compilation
yields:

Maybe something like

#ifndef CLOCK_BOOTTIME
#define CLOCK_BOOTTIME 7
#endif

will help?   The Linux kernel will return -EINVAL if the running
kernel doesn't have CLOCK_BOOTTIME implemented, so it's save to wildly
try that value.
