You have to add the library to the path or add the path to the library search path and run ldconfig to update the library. In my case it was in the '/opt/MegaRAID/MegaCli' directory where the library file was so I simply just added that to the '/etc/ld.so.conf' directory then ran ldconfig. After doing so, no more library errors. Problem now is just finding the card. Hopefully whoever sees this later will not pull their hair out. I have to stick with the Debian base because Proxmox runs as a Debian system, not as a RedHat/Fedora/CentOS system.
