The Fingerer is not part of the current open source release.
Afaik it is delivered with the "normal" commercial EigenD 2.0 though, you don't need Pro (this just adds Workbench) (Disclaimer: I have Pro, so I can't doublecheck).
If you build the 2.0 branch of the open source release yourself, you can copy over all missing agents from the commercial release (audio agent, fingerer, strummer etc. - best do a compare of the directories) and they should work. (The 2.1 experimental development branch is not fully downwards compatible to 2.0, so e.g. the binary audio agent from the commercial 2.0 release does not work. So you have to wait for a proper 2.1 release here.)
