When compiling programs under my redhat 5.1 install I get the following error message Warrning Clock Skew Detected Build may be incomplete my hardware is PII-266 MHZ SuperMicro Mother board 32 Megs of SDRAM Promise HD controller and seagate 9140A 9 Gig drive Generic VGA controller
This sometimes occurs if the time stamp of the source files are dated in the future in relation to the actual system clock. Make sure that your system clock is set correctly and reboot the machine. Then try your compile again.
This is not a bug but a feature of make. I usually see the message when building on an NFS mounted file system where the NFS server has a different time than the machine I am building on.
