Kramar,
That's odd. I'm running RHEL 5.6 x64 with HUK 5.3 without those libraries and I'm not having any issues:
[jlempka@oraracs01 ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
[jlempka@oraracs01 ~]$ rpm -qa | grep netapp
netapp_linux_host_utilities-5-3
netapp.snapdrive-4.2-1
[jlempka@oraracs01 ~]$ uname -a
Linux oraracs01 2.6.18-238.12.1.el5 #1 SMP Sat May 7 20:18:50 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
I suppose it's possible that the files contained in those packages you list are in other packages in RHEL 5.6 which I have installed, but I definitely DO NOT have the four packages you listed installed on my system.
Hope this helps.
Thanks!
Jason
