FreeBSD 11 packages built with clang 3.8

[Max Khon]

Hello!

ports/www/node package (from here:
http://pkg.freebsd.org/FreeBSD:11:amd64/latest/All/node-8.4.0.txz) seems to
be built on FreeBSD 11.0 with clang 3.8:

root at vdev3:~ # grep llvm_version /usr/local/include/node/config.gypi

                 'llvm_version': '3.8',

root at vdev3:~ #

As a result the fixes for clang 4.0 build from here
https://github.com/nodejs/node/pull/14077 do not work so "npm install"
fails as here:

https://github.com/nodejs/node/issues/140768

Is it possible that package build cluster configs will be updated to
FreeBSD 11.1 or the port should be changed to detect clang version
dynamically (at run time instead of build time).

Thanks,

Max
