The instructions posted above appear to be focused on installing rpms downloaded from somewhere, but not SuSE repos ?
I generally find it best to use rpms from SuSE repositories when they are available.
They are not always the most recent versions, but have been tweaked for the SuSE UI in many cases.
In this case, dropbox 0.7.1 can be found in the Repository HERE
Also, you will find dropbox-servicemenu 0.15.4 HERE
Add those repos, install the rpms with Yast.
(The following is KDE centric)
After install, you will find dropbox.desktop in /usr/share/applications/dropbox.desktop.
Copy dropbox.desktop to your desktop folder.
Click on the icon, dropbox will start and walk you through setting up an account (or connecting to existing one).
Once installed, if you right click on a file in Dolphin, you will see a series of Dropbox options in the Pop-Up Menu, such as copy the file to your public folder.
You might have to restart Dolphin (if running while Yast installing) to get the new service to appear in the menu.
You can check your installation , in a konsole window
A good starting point for Package Searches can be found HERE.
carl@PVE-LinuxSRV5:~> rpm -qa |grep dropbox
Be aware that "Factory" repos represent the bleeding edge, and you might get bloody using them unless you are careful, as many packages there have advanced dependencies that can muck up your system when they install. Use with caution.
Good luck, Dropbox works well here.
