GCC does not tell the linker to set RPATH unless explicitly requested, see http://gcc.gnu.org/faq.html#rpath > So I will rebuild gcc with LD_RUN_PATH=/usr/local/lib:/usr/local/gcc4/lib64 and see what > I get. That's what I've done when building on Solaris, although in my case it was for the runtime libs, not the gcc executables (see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32354#c9). There has been a suggestion to add a new configure option to set RPATHs, see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45508#c10
