Unable to run build-argon.sh

[TunaYagci]

This runscript will attempt to clone and build a custom version of argon2i for use with this miner.
It will also modify the run.sh file to use the built version of argon2i.
It requires git, make, and gcc to be installed. It assumes you have a 64 bit cpu.
fatal: destination path 'arionum-argon' already exists and is not an empty directory.
Already up-to-date.
We will use master branch, as it is the most stable arionum-focused trimmed release of argon2i available.
Already on 'master'
Your branch is up-to-date with 'origin/master'.
Already up-to-date.
By default we will use a variety of flags to ensure best build for 64 bit x86 compatible hardware.
 You will need to customize these flags if on other architectures.
build-argon.sh: 24: build-argon.sh: make: not found
cp: cannot stat 'libargon2.so.1': No such file or directory

lscpu returns:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit

It also doesn't work on OSX High Sierra, with output:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libargon2.a(thread.o) has no symbols

Another question: run.sh seems to work without any problem. What is the log that I should see? There is no accepted by pool log, only current h/s.
