 find a version of gcc on osx lion that actually compiles it --- and as far
 as I can tell, it may require some version of clang (??? possibly ???).

 The log you attached shows that you are on OS X 10.6 Snow Leopard, not
 Lion.

 The povray port does not specify a compiler, so it uses the default
 compiler MacPorts specifies. You appear to have Xcode 3.x, because
 MacPorts has chosen to use GCC 4.2 to compile this port.

 You should report this problem to the developers of povray; they need to
 fix it to be compatible with GCC on OS X. You could point them to
 [http://lifecs.likai.org/2010/05/mac-os-x-thread-local-storage.html this
 page] which seems to explain the problem. It compiled fine for me on
 Mountain Lion with Xcode 4.4 and clang, so presumably clang does now have
 an implementation of thread-local storage (and that page does not mention
 that).

 select gcc before port install)

 Most ports including povray deliberately do not use what you set with
 "port select gcc". If you want to specify a different compiler, you would
 do it like this:

 {{{
 sudo port clean povray
 sudo port install povray configure.compiler=clang
 }}}

 or:


 {{{
 sudo port clean povray
 sudo port install povray configure.compiler=llvm-gcc42
 }}}
