Debugger entered--Lisp error: (void-function define-elnode-handler)
its possible to work around the issue by evaling elnode.el so the define-elnode-handler macro becomes defined, and then again execute the upgrade.
so basically it appears the macro has not been defined when autoloads processing is happening. hopefully an easy fix.
#46 fix the autoload problem, ALSO move elnode-db to external depend.
All fixed I think.
