The port has been pinned to 2c92afb (2021-10-04) since it was added.
Upstream has landed exactly one commit since then, ba13cfb (2025-10-24),
"Replace deprecated functions for OTP 27":

• case code:lib_dir(erl_interface, Subdir) of + case code:lib_dir(erl_interface) of ...
• Dir -> Dir + Dir -> filename:join(Dir, Subdir)

code:lib_dir/2 was deprecated in OTP 27. It is not removed in OTP 28 or
29, so this is not a build fix for the tree as it stands today: the
current port still works against lang/erlang 28.5.0.5. It is
future-proofing, and it silences the deprecation warning on the code
path every NIF build goes through when resolving the erl_interface
include and lib directories.

The repository has never tagged a release, so the gYYYYMMDD version
scheme is kept 😅 taking the date from the committer date of ba13cfb, the
same convention the existing g20211004 used for 2c92afb.

poudriere testport, 14.4 amd64, x11 set: build succeeds (Built: 1,
Failed: 0), "No pkg-plist issues found (check-plist)".

portclippy Makefile is clean.
portlint -AC is clean; check-license validates APACHE20 with exit 0.

The single installed file bin/enc is unchanged in layout; NO_ARCH=yes
and PLIST_FILES still hold.
