Hi ports --

An alpha-rc1 version of lua-5.4 was announced yesterday:
http://lua-users.org/lists/lua-l/2019-05/msg00348.html
Enclosed is a WIP port plus scaffolding. One unfortunate caveat is that
you have to comment out MASTER_SITES from lang/lua/Makefile.inc in order
to fetch the tarball since it's being hosted in a different place at the
moment.

This port is mostly just `cp -R 5.3 5.4' with rote changes. Note that
one of the patches for 5.3 goes away in 5.4 because there is a new
random subsystem.

Obviously not for OK just yet but I figure others might want to look at
this early too.

Only run on amd64 right now but I'll find time to run it elsewhere in
the coming days.
