It looks like you have build using older makefiles with newer code.
With the side effects that some cpp files didn't get included. Try and
cleanup your environment et rebuild from scratch.

This usually happens if you disable maintainer mode in configure, you
have disabled some timestamp on your file system or you have change the
time on your system.
