Because "command not found" does not correspond to a standard error code (see e.g. http://linux.die.net/man/3/errno).

There is no "command not found" error that can be returned from execvp. The closest is ENOENT, which means that the file specified (or its interpreter, or a required dynamic library) was not found.
If you want, your program could print out "command not found" rather than the text returned by strerror.
