Grasping at straws, but could this be related to OS X's
case-preserving filesystem?  Could you somehow be ending up with both
"makefile" and "Makefile", where the former is the original one and
the latter is your version with changes?  GNU make looks for the
former first, which would explain the behavior, but I don't think it's
actually possible to have both those files in the same directory on a
case-preserving filesystem...

Anyway, I suggest you check your filenames carefully and use the -d
option to see what file(s) make is actually reading.
