 My llvm-g++-4.2 isn't able to compile anything using STL:

 {{{
 $ echo "#include <vector>" | /opt/local/bin/llvm-g++-4.2 -xc++ - 2>&1 |
 head -10

                  from <stdin>:1:

 llvm-gcc42 and the headers in /usr/include/c++/4.0.0 seem to disagree on
 the platform name:

 {{{
 $ /opt/local/bin/llvm-g++-4.2 -dumpmachine
 ppc-apple-darwin9
 }}}

 but:

 {{{
 $ ls -d /usr/include/c++/4.0.0/*apple-darwin9 | cat
 /usr/include/c++/4.0.0/i686-apple-darwin9
 /usr/include/c++/4.0.0/powerpc-apple-darwin9
 /usr/include/c++/4.0.0/powerpc64-apple-darwin9
 /usr/include/c++/4.0.0/x86_64-apple-darwin9
 }}}

 As a workaround I created symlink ppc-apple-darwin9 pointing to powerpc-
 apple-darwin9, which seems to make llvm-gcc42 work flawlessly.

 {{{
 $ ln -s powerpc-apple-darwin9 /usr/include/c++/4.0.0/ppc-apple-darwin9
 }}}
