Comment (by kencu):

 I'm glad that worked for you.

 However, I had some time to redo the experimental ppc section of the
 [wiki:LibcxxOnOlderSystems] instructions, and guess what? It still works:

 {{{
 $ port -v installed libcxx
 The following ports are currently installed:
   libcxx @5.0.1_1+universal (active) platform='darwin 9' archs='i386 ppc
 x86_64' date='2018-01-20T09:09:03-0800'
 }}}

 libcxx still installs with a ppc slice without any trouble on Leopard,
 building it with clang-3.7.

 The OP's issue is something different yet. Perhaps the "undoing" of the
 instructions somehow led to gcc-4.2 being called in.

 The idea that gcc won't build libcxx with the existing MacPorts Portfile
 remains accurrate. Exactly what failed for the OP to lead to gcc being
 asked to build libcxx is less clear.
