Do this command:

rpm -q openib

It seems that the version in EL4 has a newer number than the version in EL5:

el4:  openib-1.1-7
el5:  openib-1.1-5.el5

If you have openib-1.1-7, then you need to download and install version
1.1-5.el5 .. this may require upgrading all things that depend on openib
as well.

Thanks,
