Yah. I got to this point later in my note. But I see the problem now...

Ah. Good.
[ I probably did that on purpose for the new build stuff, but simply forgot.
Those --rpath things are needed for the code to run at all. ]

Yup.

They are *not* supposed to be in there. That is entirely correct.
The libraries are dynamically loaded when needed. We don't depend upon the
run-time link loader to do it (we make explicit calls).
So... either install them, or set your LD_LIBRARY_PATH.
The alternative is some more configuration work. Essentially, there are
three ways for us to deal with the ra_* libraries:
1) link them all in, statically
2) link them all in, as shared libs
3) load them as shared libs
Our current system implements (1) and (3). You were expecting (2), which we
don't have without some autoconf stuff to allow selecting between 2 and 3
when shared libs are built.
