I did a git clone and i merged my files with the fresh install and it
works ok now.
I have seen this problem too many times (make fails after git pull) so i
keep many copies of my builds.
In any case it would be nice to know what caused the build to fail
because the only thing i did is to clone a fresh copy of the master so
there must be a change that causes the problem or if i miss an update
maybe a file is not the correct version anymore.
