Re: Why does ltmain.sh::temp_rpath not need the same system lib considerations?

Normally if you call the generated wrapper scripts, things should be 
ok, as long as the linkage was correct in the first place.

I don't think that it is normal or ok to have the system library path 
in the list at all.  Perhaps libtool is not determining that the path 
is a system library path.

Check the output of './libtool --config'.  Particularly, 
sys_lib_dlsearch_path_spec.  Maybe it is wrong.
