Building FR 4.0 on Ubuntu 16.04.1

[Alex Sharaz]

Trying to build FR 4.0 on This flavour of Ubuntu and I get

root at prodn2:/usr/local/src/freeradius-server-4.0.x# make
scripts/boiler.mk:628: src/modules/rlm_lua/rlm_lua.mk: No such file or
directory
scripts/boiler.mk:628: src/modules/rlm_lua/libfreeradius-lua.mk: No such
file or directory
make: *** No rule to make target 'src/modules/rlm_lua/libfreeradius-lua.mk'.
Stop.

What do I need  to install to get a bit further?
