Effectively, new installs of macports are not happening for a while then
(as I just figured out). Anybody have a hack/workaround?
No. You just have to explicitly pass '--with-build-config=bootstrap-debug'
to configure when building with the clang 3.5 or later from llvm.org or
with Apple clang 6.1. The code in configure that tests for proper debug
code in object files is tripped up by this breakage in clang (where the
wrong CIE version of dwarf 3 is emitted in the absence of debug flags).
