Try looking very critically at the system date and time:
 $ date

This check is comparing the system time to the timestamps of
the files on disks to try to detect whether your system clock
is correct.  Since the 'make' program relies on comparing timestamps,
you can get very strange results if your system clock is not consistent.

You can use the date utility to set the system clock to
the approximately correct time (it doesn't need to be very
exact).  If you have networking, you can use "ntpdate pool.ntp.org"
to set the clock from the network.
