Having recently heard of this program, which is still in beta stage but perfectly usable I've found, I wanted to install it and try it out. So I downloaded the relevant package from their site, unpacked it and then navigated to its directory and then did -
sudo rpm -Uvh *.rpm
and then just left it to install all the necessary rpms with very good effect. But I did find that I couldn't load in the desktop/menu shortcuts to it as that would override the OpenOffice ones, and I want to keep that as a backup for me just in case Libreoffice goes belly up! So I still had to create manual shortcuts and menus for it, but that's easily done.
