[ESS] ESS + Gnu Emacs on OS X questions

[Seth Falcon]

Hi all,

A couple of question on ESS behavior with Gnu Emacs on OS X:

(1)
I'm not able to use the feature where you hit C-c RET in an ESS (R) 
buffer and get the current line moved to the prompt at the bottom of 
the buffer so you can edit it.

This works for me on Linux, but not on OS X.  I get an error message 
like so:

comint-insert-input must be bound to an event with parameters

This was happening with the prior ESS release as well as the recently 
released code.

(2)
The first time I load an Sweave type file after starting emacs, I see 
messages like the following:

In a buffer called *Compile-Log*:
Warning: `error' called with 1 args to fill 0 format field(s)
Warning: `error' called with 1 args to fill 0 format field(s)
Warning: `error' called with 1 args to fill 0 format field(s)

Can someone give me a pointer about tracking down what this is about?  
I notice that I get the same messages when I first load a *.R file as 
well.


I'm using Emacs 21.3.50.1 from CVS.  ESS is 5.2.4.

Thanks,
