 Hi, I'm trying to follow the guide listed here:
 LibcxxOnOlderSystems

 At step 7, running the line as written

 `sudo port -v -n upgrade --force --enforce-variants cctools -llvm34
 +llvm39`

 fails with Error: `cctools: Variant llvm39 conflicts with llvm40`



 running the line modified to include llvm40

 `sudo port -v -n upgrade --force --enforce-variants cctools -llvm34
 +llvm40`

 gets further but still fails with

 `In file included from /usr/include/limits.h:64:`

 `/usr/include/machine/limits.h:10:2: error: architecture not supported`

 `#error architecture not supported`

 and requests that I submit a ticket.

 I'm running Snow Leopard 10.6.8 on a Macbook Pro 5,3

Comment:

 The log you attached contains 6 failed build attempts.

 The first one failed with these errors:

 {{{
 :info:build cp:
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_llvm-3.7/clang-3.7/work/build/tools/clang/runtime

 directory

 /compiler-rt/clang_darwin/10.4/libcompiler_rt.a: No such file or directory
 }}}

 Build attemps 2 through 6 failed with this error:

 {{{
 :info:build /usr/include/sys/cdefs.h:540:4: error: Unknown architecture
 }}}

 However those build attempt were not clean; they were resuming from the
 original failed build. As such, I would not pay any attention to the
 possibly erroneous errors they generated and I would focus on the error
 generated by the original build attempt.
