Thanks for the reply.
What is unclear to me is why, if LFS is going to leave the loader in /lib64, go
to the trouble of installing glibc libs to /lib and gcc libs to /usr/lib - it
would seem logical that everything either goes in:
/lib, /usr/lib, /usr/local/lib
Or
/lib64, /usr/lib64, /usr/local/lib64
It's true that a few pre-built binaries - Firefox, Skype - expect the loader to
be in /lib64, but I suspect this will change soon.

John
