If you are receiving the following error:
Packages "bind-libs-30:9.3.4-6.P1.el5.i386 (u 0x8e94748 source=0x8b49958 P:22 R:19)" and "bind-libs-30:9.3.4-10.P1.el5.i386 (s 0x8ae9358 source=0x8aa3f38 P:22 R:19)" cannot be installed at the same time because of the conflict on the file "/usr/lib/libbind.so.4"
This is because Redhat Linux 5 has a later version of libbind.
To resolve the problem remove the latest versions of libbind from the OS:
rpm -qa | grep bind
Remove the packages listed one by one:
rpm -r [package name
