Thanks for changing this to a warning.  However, I still get this
warning every time I build.  Could it be changed (again) to only warn if
if yapp was found and it used it?

Otherwise (in the absence of an alternate solution), I fear that many of
our git-following users will keep getting this warning every time they
build.
