If I understand correctly, this translate to an equivalent to "gcc
-R<$ORIGIN>" with $ORIGIN being a
relative path -- that is, simply using -R option with relative paths.
While being fine for executables, I suspect that this is not really
appropriate for boost.python wrapped
libraries, where
- libboost_python.so would probably reside in
- the wrapper library shared object would probably reside in
- the wrapped library resides anywhere on your system

Running python and using this extension is now dependant from where you
invoke the interpreter;
it will only work if the wrapped lib can be found in the relative path
So it is either LD_LIBRARY_PATH again (not good) or adding some search
paths with -R in
the link step, the search paths being s.th. like site-dependant standard
library installation directories.
E.g. a shared filesystem named /apps/prod where I would install central
components (like python :-)

Anyway, thanks a lot for all the hints!
