I uninstalled all packages built with GCC 6 and re-activated the old
outdated versions. Then I built `py27-cython` with GCC 5 and installed it.
This allowed `port` to upgrade or re-install nghttp2 and curl which
depends on it. On this basis `port` could build `clang-3.9` and
`llvm-3.9`. Afterwards `port` could upgrade some 40 packages. `Gcc5` is
the last outdated package. This is the sequence in which the packages were
built:
