The "kendo.all.d.ts" comes with the kendo ui full license. That said, you can get a copy from here : http://www.kendoui.com/forums/ui/general-discussions/typescript-definition-file-problems.aspx
But a) its not up to date, b) Will contain definitions for things that are not a part of kendo opensource.
Solution: Fix the missing definitions yourself. If you are having difficulty and want a quick start you can always do:
(<any>kendo).observableHierarchy
And typescript will not complain.
