I don't think there has been a "release" of merb 0.4. You need to report
your subversion revision number, as shown by "svn info":

$ svn info
Path: .
URL: http://svn.devjavu.com/merb/trunk
Repository Root: http://svn.devjavu.com/merb
Repository UUID: 47880103-7c1f-0410-8e14-d6dd2138f79d
Revision: 516                <<<<<<<<<<<< this number
Node Kind: directory
Schedule: normal
Last Changed Author: ez at brainspl.at
Last Changed Rev: 516

I only say this because if you are running r422 or later, you should get a
more helpful error message ("no template matching <list of extensions>")
rather than "undefined method `transform' for nil"

Brian.
