nslookup, dig and other commands giving a Segmentation fault with RedHat

If you are using later version of redhat that uses a 2.4 kernel and you compile your own standard kernel from ftp.kernel.org then some apps may no longer work. this is because Redhat patches their 2.4 kernel with Native POSIX Thread Library (NPTL) support that only exists in standard 2.6 kernels.

Any application that is compiled against Redhat's shipped kernel will now be broken giving a "Segmentation fault" when run. To fix this you can either go back to the Redhat supplied kernel, upgrade to 2.6 or try and path a standard kernel.
