Hi, I'm trying to follow the guide listed here:
https://trac.macports.org/wiki/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
