backquote errors with emacs24

[Matt Price <matt.price@utoronto.ca>]

 hi folks,

I noticed that the latest debian package for flim included the 
much-awaited backquote fixes for emacs24.  So I installed a recent 
emacs-snapshot (2010-10-31) and yay! flim compiles, but when running wl 
I get this error:

Loading /home/matt/.emacs.d/wl/wl-send-html-message.el (source)...done

Auto plugged off at mailbox126.utcc.utoronto.ca:993
byte-code: Invalid function: (\` (start-process name buffer 
ssl-program-name ((\,@ ssl-program-arguments))))

I figured (blindly) that this was a backquote issue but changing the ` 
to "quote" nets me this instead:

byte-code: Symbol's function definition is void: \,@
Mark set

I'm sure this is blindingly obvious to most people on the list - -can 
you tell me how to fix it? thanks,
matt
