 Darwin/PowerPC support is still quite experimental in llvm, so expect things to not be as stable as more established toolchains.  Additionally, it is non-trivial to bootstrap libc++ on Leopard because the libcxx port does not build for ppc with versions older than clang-3.6, and clang-3.5 and newer require libc++.  After setting up my Leopard/Intel Mac as described above (fully upgraded through 1ad7738a54d1bb11c98455154e6d625680f49b2d), I've been able to build a universal libc++ runtime for ppc:
 {{{
 # clang-3.6 or newer is required for compiling ppc code with clang
-sudo port -v -s install clang-3.6
+sudo port -v -s install clang-3.7
 
 # Uninstall the intel versions of these ports
 sudo port -v -f uninstall libcxx libcxxabi libmacho libunwind
 
 # Re-build libcxx, libcxxabi, libmacho, and libunwind with a ppc slice
-sudo port -v -s install libcxx universal_archs="x86_64 i386 ppc" configure.compiler=macports-clang-3.6
+sudo port -v -s install libcxx universal_archs="x86_64 i386 ppc" configure.compiler=macports-clang-3.7
 }}}
 
 With this, a simple PPC C++ "Hello World" app was able to run successfully on an Intel Mac.  Not much more testing has been done than that.
