Author of reactive-banana and threepenny-gui here.
One of the design goals of Threepenny is to be dead simple to install.
Please keep reporting things that don't work. In your case: Are you
trying to run the Button.hs file from github? This one is coded
against version 0.6.*, which has not been released on Hackage yet.
Please use the Button.hs file included in
instead, or run the threepenny-examples-buttons executable.
As for reactive-banana-wx: There's a reason I started Threepenny. :)
