I hope, this really works. I really am loocking forward to seeing int 
working on first try. :-)

On what platforms is using of RPATH discouraged?

Using RPATH is not a matter of advice or platfom but of necessity. 
Either setting rpath is required for an appication to access a specific 
lib or it is not. This is not a matter of the platform used but of a 
configuration decision of the person, that installed that library.

For any program that depends on libraries other than the basic system 
ones (-lc, -lm, -lresolv, ...), configure should check wether linking 
with -lfoo requires setting rpath or not.

My suggestion is to first compile the probe programs with rpath and if 
the probes show, that lib is available and usable to do additional test 
to determine, wether rpath componentes can be safely omitted.

73, Mario
