Hello Adam,

Thanks for working on the libressl topic, definitely a useful change.
See some comments below.

Why is this entire commit log indented with 4 spaces? Could you just
start the lines, well, at the beginning of the lines?

Please use the "github" helper function instead.

Or even better, use release tarballs from
http://ftp.openbsd.org/pub/OpenBSD/LibreSSL/. This way, you don't need
to call autogen.sh.

Where do this license list comes from?

I don't see any file named "COPYING" in the repository at
https://github.com/libressl-portable/portable/tree/v2.5.4.

Not needed if you use the release tarballs, as suggested above.
