can't build node-sass under FreeBSD 11.1

[oschonrock]

Duplicate of the (closed) #14076

I still have problems building node-sass (under gyp) on FBSD11.1.

In order to get the fix in mat813/freebsd-ports@cea3aae now, I updated to latest packages:

# cat /usr/local/etc/pkg/repos/FreeBSD.conf
FreeBSD:{
 url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest"
}

and then

pkg install npm-node8

New packages to be INSTALLED:
 npm-node8: 5.4.2_2
 node8: 8.9.1_1

but still

$ npm install node-sass

If you're using the ports version, you should report the issue there. If it needs coordination with us, the ports maintainer will forward it to us. It was fixed here in v8.3.0, see #14077.

OK. Have emailed port maintainer.

I solved it. It was to do with how the binary node8 package was being built in the FreeBSD pack build infrastructure. TLDR; it was being built under FBSD 11.0 (clang3.8.0), and if you then run it on a FBSD11.1 (clang 4.0.0) machine the gyp build (of eg node-sass) will fail with above error. Building the port from source on local machine always works.
