The reason is that I need to work around restrictions in R about how and I
where I can build libraries.  And e.g. the complete lack of follow-up from R
Core about the suggested additions to the R CMD INSTALL functionality (cf
r-devel in the summer).

Rcpp builds and works for me under Linux and Windows -- the only platforms I
have access too -- and I use it daily.  I had asked a friend who uses OS X to
test this, but he hadn't gotten around to it.  So OS X is simply untested.

On Windows and Linux I now install one copy of Rcpp and have other package
compile and link against it.

| Just to get you started, *remove* src/Makefile and create the  
| following src/Makevars:
| 
| all: $(SHLIB) userLibrary
| 
| USERLIB=libRcpp$(DYLIB_EXT)
| USERDIR=../inst/lib
| 
| userLibrary: $(USERLIB)
| 	- at if test ! -e $(USERDIR)$(R_ARCH); then mkdir -p $(USERDIR)$ 
| (R_ARCH); fi
| 	cp $(USERLIB) $(USERDIR)$(R_ARCH)
| 	cp Rcpp.h $(USERDIR)

The platforms I work on don't need the $R_ARCH stuff which is why I didn't
add it.  If this is portable, we can surely talk about making it more
generic.  

If David is willing to test this, we can probably sort this out over a few
off-list emails. I'd be up for that.

| $(USERLIB): Rcpp.o
| 	$(SHLIB_CXXLD) -o $(USERLIB) $^ $(SHLIB_CXXLDFLAGS) $(ALL_LIBS)
| 
| .PHONY: 	all clean userLibrary
| 
| clean:
| 		rm -f $(OBJECTS) $(SHLIB) $(USERLIB)

That is overall a pretty small change.  So I don't see the need for the
belligerent tone above, especially given that I have no access to OS X.

Thanks, Dirk
