On the top of first-setup.sh there is

#!/bin/sh

# Takes the same arguments as mtx-update

# you may change this if you want ...
CONTEXTROOT="$PWD/tex"

and some lines from the bottom
env PATH="$PWD/bin:$CONTEXTROOT/texmf-$platform/bin:$PATH"


On my linux box I see, given that I'm installing
under /opt/luatex/standalone-mkiv-test,
$ export|grep PWD
declare -x PWD="/opt/luatex/standalone-mkiv-test"


Perhaps your box doesn't  set PWD correctly ?
