darktable @2.2.5_1+quartz compile error

[saherr1969 (Stephen H)]

Trying to install darktable per the darktable.org/install instructions:
sudo port install darktable +quartz

It failed so I checked for OS and Application updates in App Store.
-- Performed 9.2 Xcode upgrade
-- Performed 9.2 Command Line Tools (macOS Sierra version 10.12) for Xcode
-- Performed 10.12.6 Security Updates (required Restart)

Then I performed the following:

It appears this is the key error section (line numbers added to help):

This appears to be an issue with lua5.3 which deprecates _luaL_checkint and other such functions. Uninstalling lua and installing lua52 seems to work.

[saherr1969 (Stephen H)]

So I checked on lua:

port installed|grep lua
  gnuplot @5.2.2_0+aquaterm+luaterm+pangocairo+wxwidgets+x11 (active)
  lua @5.3.4_1 (active)
  lua52 @5.2.4_1 (active)

The 5.3 version is tied to gnuplot which in turn is tied to octave.

Is it possible to point the darktable install at lua52 somehow during compile time?

Thanks!

The issues with lua (5.3) conflicting with lua-5.2 are apparently well known:

​https://trac.macports.org/ticket/46880

I've tried various things but I can't get the darktable build system to ignore the headers from lua 5.3. Only approach I can find is to use conflicts_build to work around the problem.
