Instructions to build DMD from source don't work (anymore) here

[Basile B.]

Hi, I've recently switched from a linux distribution to another 
(F27). During the last 2 years i used a script to build DMD, 
unfortunately i forgot to include it in my backup. Initially i 
thought "No problem, there's the instructions in the wiki, it's 
more or less about calling make with a couple of option". In 
theory only...

make -fposix.mak gives me

All required tools are setup. I do not set AUTOBOOTSTRAP=1 since 
dmd 2.077 is setup.
