 On OSX 10.6.8, I was failing to follow these instructions:
 LibcxxOnOlderSystems including the older version here:
 https://web.archive.org/web/20170331190323/https://trac.macports.org/wiki/LibcxxOnOlderSystems

 The output was one cycle, among many, was:
 {{{
 sh-3.2# port install clang_select
 --->  Scanning binaries for linking errors
 --->  No broken files found.
 --->  Found 5 broken ports, determining rebuild order
 You can always run 'port rev-upgrade' again to fix errors.
 The following ports will be rebuilt:
  ncurses @6.1
  gettext @0.19.8.1
  llvm-3.4 @3.4.2
  cctools @895+llvm34
  ld64-127 @127.2+llvm34
 Continue? [Y/n]: Y

 sh-3.2#
 }}}

 I ended up fixing the problem by changing my universal architectures in
 /opt/local/etc/macports/macports.conf
 as follows:

 {{{
 # CPU architectures to use for Universal Binaries (+universal variant)
 #universal_archs                i386 ppc  # breaks libcxx binary support
 universal_archs         i386 x86_64
 }}}

 which enabled me to find the prebuilt libcxx here:
 https://packages.macports.org/libcxx

 Anyone whose macports started out on OSX 10.5 could have this problem.
 Should it be documented on, or linked from the libcxx page above?
