Hi All,

I'm getting an inscrutable error when using the regular zeroconf (curl https://get.pharo.org | bash) and trying to run the resulting ./pharo script:

��

```

ioLoadModule(/home/egade/ui-test-1/ui/test/pharo-vm/lib/pharo/5.0-201901051900/libgit2.so):
�� libz.so.1: cannot open shared object file: No such file or directory
ioLoadModule(/home/egade/ui-test-1/ui/test/pharo-vm/lib/pharo/5.0-201901051900/libgit2.so):
�� libz.so.1: cannot open shared object file: No such file or directory
tryLoading(/home/egade/ui-test-1/ui/test/pharo-vm/lib/pharo/5.0-201901051900/libgit2.so/.libs/,libgit2.so): stat(/home/egade/ui-test-1/ui/test/pharo-vm/lib/pharo/5.0-201901051900/libgit2.so/.libs/) Not a directory
External module not found

```

This is on an Ubuntu server that is (unfortunately) running 14.04 LTS. For the time being the version is out of my control.

I have tried something like `apt-get install zlib1g` but the system is reporting that this is already installed. From this error message I cannot really tell what the actual problem is and I'm also a little stumped about how to properly debug it.

Tips in any direction are much appreciated. Thanks!
