You need to uninstall any ports built using 4.0, then uninstall
clang-4.0 and llvm-4.0, then reinstall the ports you need using clang 3.9.

Doesn't work.
The following ports will break:
cctools @895_4
ld64-latest @274.2_1
I selected "y" anyway, but as expected, got the same error message:
cctools: Variant llvm39 conflicts with llvm40

sudo port uninstall clang-4.0 llvm-4.0 should do it for you.
don't forget to change the line in macports.conf about
default_compilers, removing clang-4.0.
BTW I appear to have fixed clang-4.0 for snow leopard, and depending
on what Jeremy wants to do with that, it should be working in macports
or upstream eventually.
Although I'd recommend you stick with clang-3.8 or clang-3.9 for now,
clang-4.0 for snow leopard will work soonishly. There's a word... :>

I forgot, but how do I uninstall the broken llvm40 version?
On Step 7, it complains about conflict between llvm39 and llvm 40.
Thanks

Hello there,
I needed to reinstall MacPorts on Snow Leopard, and followed the
instructions in LibcxxOnOlderSystems (I recall some ports wouldn't
compile properly without it), including the experimental steps.
Only there, I replaced clang 3.9 by clang 4.0.
However, it failed on completing xsane compilation, as glib2 failed:
/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_glib2/glib2/main.log
is pasted there:

From what I could read, it can't find a given header file. How did
it went missing?
As mentioned privately, it seems likely you've stumbled across this
bug <https://bugs.llvm.org//show_bug.cgi?id=31504> which Jeremy
reported a few months ago.
It looks like a new regression and I don't see that error on 10.6
with clang-3.7, clang-3.8, or clang-3.9, so if you back up in the
libcxxonoldersystems instructions and install clang-3.8 or clang-3.9
you should be OK.
I haven't tried clang-4.0 to confirm this bug / error on my system
yet, but I could assume I'd see it too if I did.
Best,
Ken
