./bootstrap: line 14: [: argument expected
Current system time is set to: Sat Dec 18 0923 EST 2010
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!
Unable to verify system time. Utility to set time from a remote host, rdate, is not installed in PATH.
If your system time is skewed greater than a few hours, then source compilations will subtly fail.
This may result in an overall installation failure.
