GNU Modula 2 in non Debian based Linux

[Georgios Odysseus Papadopoulos]

Hello to all!
I am new to Modula2. Essentially, I am trying to become new.

My problem:
My distro is Void Linux and there is part of the gnu collection 
(13.2.0_2: ada, go, fortran, objective-c) but unfortunately gm2 is missing.
So my problem is twofold
a) I have to find my way on (compiling/installing) the corresponding 
version of gm2 (for, as far as I know, it is not wise to have to 
separate gcc collections with different versions)
b) in the official site, some links like e.g.,

git clone http://floppsie.comp.glam.ac.uk/gm2 gm2-floppsie

simply do not work!
So, is there somewhere, the needed steps and working links to find my 
way to GM2?

Thank you in advance!
Regards
