Comment (by kencu):

 Most likely a duplicate of [ticket:54798]

 To build webkit2-gtk with the system clang on many systems, I had to add
 `configure.cxxflags-append -std=c++14` to the Portfile.

 Alternatively, you can most likely build `webkit2-gtk-devel` as the issue
 seems fixed in that newer version. (Pretty soon we'll make that
 `webkit2-gtk` I think.) In most cases, `webkit2-gtk-devel` will satisfy
 the dependency.

 Finally, if no happiness is coming your way, you can most most likely
 build `webkit2-gtk` using `clang-4.0` which seems happier building it.
 First you have to install it `sudo port -v install clang-4.0`, and then
 when that is done, `sudo port -v install webkit2-gtk configure.compiler
 =macports-clang-4.0`.

 If you're impatient, that last option is the most reliable way to get
 going.
