AFAIK there are no smartmontools rpms for version 5.39.1 for anything but fedora.
Here is a src rpm, and x86_64 binary that works with Scientific Linux 5.3, and probably centos.

I just took the spec from here:
ftp://194.199.20.114/linux/sourceforge/s/project/sm/smartmontools/smartmontools/5.36/smartmontools-5.36-1.src.rpm

Updated the version and source code and built the rpm. This was done because there are no current centos/scilin rpms for smartmontools which support MEGARAID cards.

smartmontools-5.39.1-1.x86_64.rpm

smartmontools-5.39.1-1.src.rpm

IN PROGRESS

Gipplet is an rpm for gnome which puts the ip in the taskbar. I liked it for users that didn’t know how to find their own ip, it makes coaching them over the phone a bit easier.

I built the rpm from source, ill post its specs soon.

http://giplet.sourceforge.net/
