>Description:
building www/chromium from pkgsrc-2026Q1 on NetBSD 10.1 amd64 (fresh install)
fails due to available clang being too old:

And indeed, we only have clang 19:

pkg_info |grep clang
clang-19.1.7nb2     C language family frontend for LLVM

head -3 /usr/pkgsrc/lang/clang/distinfo 
$NetBSD: distinfo,v 1.88 2025/05/09 05:51:24 adam Exp $

BLAKE2s (clang-19.1.7.src.tar.xz) = 36f273c5c29f396c74f69fc71bd3be3c9da789323f1a66e170752bf0a804006d


>How-To-Repeat:
Try to build www/chromium on NetBSD from pkgsrc-2026Q1, it will fail due to
clang being not new enough.


>Fix:
Update lang/clang to clang-20, I guess? Seems it was released about 1y ago.
