------------------------------------+--------------------------------
 when compiling simple 'hello world' app
 {{{
 #include <stdio.h>

 int main() {
   printf("hello world\n");
   return 0;
 }
 }}}

 clang-3.8 fails with

 {{{
 user$ clang hello.c -o hello
 dyld: Library not loaded: @rpath/libLLVM.dylib
   Referenced from: /opt/local/libexec/llvm-3.8/bin/../lib/libLTO.dylib
   Reason: image not found
 clang: error: unable to execute command: Trace/BPT trap
 clang: error: linker command failed due to signal (use -v to see
 invocation)
 }}}

 same error happens with clang-3.9, I noticed.

 code compiles correctly and llvm tools work with clang 3.7 and 3.4
 selected.

 It appears the clang 3.8 and 3.9 rpath is not finding the runtime
 libraries. I'm not certain if this is due to how they were compiled, or
 something different in my configuration that would affect only the newer
 versions of clang.

 (Clang-3.8 was installed precompiled. Clang-3.9 was installed from
 source). I'm on 10.6.8.
