[Vm-dev] [Pharo-dev] Apparently Zodiac plugin can crash VM on Linux

[Max Leske]

I've heard from Martin again:

embee
i think i figured out the problem: ZnClient works with libssl 1.0.0 but 
not with 1.1. if i force a symlink from 1.1 to 1.0.0 then ZnClient 
works, however git still fails because it links against libldap which 
links against openssl 1.1.
it looks like the way to fix this would be to make ZnClient work with 
openssl 1.1
