Can't locate module: SWANK-IO-PACKAGE::SWANK-MACROSTEP

[David Hodge]

Hi there,

I recently upgraded slime via melpa and restarting emacs produced this 
message:
   " Can't locate module: SWANK-IO-PACKAGE::SWANK-MACROSTEP"

and puts me into the common lisp debugger. Quitting the debugger aborts 
the slime start up.

I can see the swank macrostep source in the distribution ( but it has 
not been compiled yet I think) so I am hoping someone more knowledgable 
might be able to advise me how to debug this?

Best Regards
