The generic way of specifying rpath (using gcc or Sun cc driver) with the Sun linker is '-Wl,-R,dir:dir' Normally, the GNU linker (from binutils) would use '-Wl,-rpath,dir:dir' but I'm not sure if the Sun target changes this for Sun cc compatibility. You should also be able to change the default specs file (what is spat out by 'gcc -dumpspecs') to make gcc behave as desired. Unfortunately, rpath is not a general solution for shared libraries included in Sage because the paths would then be fixed at link time - which wouldn't all the Sage package to be arbitrarily relocated. -- Peter Jeremy
