I only had the libc++ setting when I started.

I went back to a pristine macports.conf

So it get's a bit further now

It has removed the work directory for llvm-3.4 :
root at 0125000629 00:48:37 /macports/var/macports/build
#=> ls -l

drwxr-xr-x  3 root  admin  102 29 Aug 00:53

According to my i386 installation :
#=> port installed name:cxx
The following ports are currently installed:
  libcxx @5.0.1_4+universal (active)
#=> port contents libcxx
Port libcxx contains:
  /macports/var/system_roots/libcxx-5.0.1-4.tgz

But this isn't present yet on the x86_64 :
#=> ls -l

It's impossible to install the remaining ports one-by-one as they all
depend on each other :

#=> port install cctools
