compiling on snow leopard: Cocoa errors?!?!?!

Dear R-gurus,

I'm trying to compile R on my new mac. It's snow leopard. So far  
I've seemed to be doing pretty well. I've looked at

http://cran.r-project.org/bin/macosx/tools/

http://r.research.att.com/exp/

http://r.research.att.com/building.html

http://r.research.att.com/tools/

All of which have been very helpful. Looking at the threads I've got  
around some X11 issues that stopped the configure script working but  
now when I excute make I get the error below. Any ideas?

Thanks in advance,

Paul
