The error in the log shows this:

If I’m right, you’ve been caught by the libcxx bootstrapping issue I have yet
to fix.
Once you have 10.6.8 with libcxx installed, and then any version of clang >=
5.0, do this:
sudo port -v -n upgrade --enforce-variants libcxx +emulated_tls
and you should be good to go thereafter.
I have to either fix this somehow, put in in the port notes, or otherwise find
a way to automate this step…
