--- Comment #2 from Bastiaan Veelo <Bastiaan at Veelo.net> ---
Confirmed:

$ curl -fsS https://dlang.org/install.sh | bash -s dmd
main: line 178: USERPROFILE: unbound variable

Workaround:

$ wget https://dlang.org/install.sh
$ chmod +x install.sh
$ ./install.sh 
$ source ~/dlang/dmd-2.093.0/activate
$ dmd --version
