The browser (extra-apps/browser) and its engine, lovely-webengine.

WPE WebKit 2.54.0 (libWPEWebKit, WPEWebProcess, WPENetworkProcess)
  LGPL 2.1 (WebCore, WebKit), BSD 2-clause (JavaScriptCore, WTF, WPEPlatform)
  https://wpewebkit.org/  Copyright Apple Inc., Igalia S.L. and others
  Built with the patches in extra-apps/browser/engine/patches (BSD 2-clause).
Skia (inside libWPEWebKit): BSD 3-clause, Copyright Google LLC.
The Khronos EGL headers (build only): Apache 2.0 / MIT.
DejaVu fonts: Bitstream Vera licence and public domain.

The engine is dynamically linked against the pkgsrc packages it is
installed with (glib2, harfbuzz, ICU, libsoup3, gnutls, nettle,
libgcrypt, libxml2, libxslt, sqlite3, libwebp, libjpeg-turbo, png,
freetype, fontconfig, libxkbcommon, xkeyboard-config, lcms2, hyphen,
woff2, libepoxy, brotli, pcre2, libffi, p11-kit, libtasn1, libidn2,
libunistring, gmp, nghttp2, libpsl, curl, libproxy, glib-networking,
shared-mime-info, gsettings-desktop-schemas, mozilla-rootcerts and
their dependencies), each under its own licence as pkg_info lists
them; the LGPL ones are met by shipping the libraries as separate
files. The browser app itself links nothing: pure Go.
