I am using kepler with out any problems so far, you can try that.
The error you get is some pre-req plug in is missin...first you may have to install the gateway odata feature plug-in..
go to help -> install new -> select Development tools for eclipse juno ( https://tools.hana.ondemand.com/juno)
select Gateway Productivity Accelator..you can select everything under it or only odata toolkit..
install it, restart and then try installing the fiori toolkit..
