Excellent work. A few issues with building
In both cases i checked out from SVN(fresh copy)
cd rprotobuf/

1) On Leopard 10.5,
it builds, but when I try to load

Loading required package: Rcpp
Error in dyn.load(file, DLLpath = DLLpath, ...) :
   unable to load shared library '/Library/Frameworks/R.framework/ 
libs/i386/RProtoBuf.so, 6): Symbol not found:  
   Referenced from: /Library/Frameworks/R.framework/Resources/library/ 
   Expected in: dynamic lookup

Error: package/namespace load failed for 'RProtoBuf'

2) On RHEL5
(uname: Linux spica 2.6.18-128.4.1.el5 #1 SMP Thu Jul 23 19:59:19 EDT  
2009 x86_64 x86_64 x86_64 GNU/Linux)
even though  I have protobuf installed
checking for protoc... yes
checking for ProtoBuf headers and library... no

   Your installation does not appear to have ProtoBuf headers and  

   Please make sure that you have a working and complete ProtoBuf  

ERROR: configuration failed for package 'RProtoBuf'
** Removing '/ln/meraki/custom/lib64/R/library/RProtoBuf'

3) I now think that it might not be useful to merge rprotobuf (which I  
plan to rename rpbsz) with this new package.
I saw the examples and there are really nice. Everything I did in  
rprotobuf can be done from within R via RProtoBuf(or wrappers around it)
and my package is just a wrapper around one proto file wherea  
RProtoBuffer can handle any proto file.
I'm thinking that it would be enough to keep the proto file i used in  
the proto directory as an example (though it is a very detailed proto
