[R-SIG-Mac] Rcpp on OSX?

[Prof Brian Ripley]

The errors I get differ from yours (are your R and Xcode up to date?) but 
the problem is a fundamentally flawed Rcpp/src/Makefile. 
Here the lines I had to change (OS 10.5.5, R 2.8.0, Xcode 3.1.1):

PKGLIB          = Rcpp$(SHLIB_EXT)

$(PKGLIB):      $(PKGOBJ)
                 $(SHLIB_LINK) -o $(PKGLIB) $(PKGOBJ)

$(USERLIB):     $(USEROBJ)
                 $(DYLIB_LINK) -o $(USERLIB) $(USEROBJ) $(LIBR)
                 @cp Rcpp.h $(USERDIR)

But, I would not start from here, rather write a src/Makevars following 
the actual R documentation.  The package may compile on Debian Linux, but 
it compiles on none of my systems, not even the Linux ones.
