That all looks correct to me.
The BitcodeReader.h file is a private implementation header located in
lib/Bitcode/Reader and it won't get installed. The BitstreamReader.h
file is the public interface to (generic) bitstream reading. The
ReaderWriter.h file should also be installed in
your /usr/local/include/llvm/Bitcode directory. This is the public
interface to reading and writing LLVM bitcode (LLVM specific bitstream
files). If this is insufficient for you then you need to talk to Chris
Lattner about making additional (private) interfaces in BitcodeReader.h
available in ReaderWriter.h
