There's a very simple way to avoid this problem in the future.
Pass --enable-maintainer-mode to the configure script. This will
make sure that when building mono it will check if the input files for the
Makefiles have changed.

This is a common oversight that I find myself doing over and over. So I
hope this helps you.
