Installing Augustus in MacOS

[aberaslop]

Hi!
I am having trouble installing Augustus in MacOS Mojave.
I am following the instructions in https://github.com/nextgenusfs/augustus

But when I try:
make CC=gcc-7 CXX=g++-7 BAMTOOLS_CC=clang BAMTOOLS_CXX=clang++ BAMTOOLS=/Users/user/funannotate/bamtools-2.4.0/

I get:

mkdir -p bin
cd src && /Applications/Xcode.app/Contents/Developer/usr/bin/make CC=gcc-7 CXX=g++-7
g++-7 -c -Wall -Wno-sign-compare -ansi -pedantic -O3 -o genbank.o genbank.cc -I../include
make[1]: g++-7: No such file or directory
make[1]: *** [genbank.o] Error 1
make: *** [all] Error 2

Does anyone know what is going on and how can I fix it?

Thank you so much!

L.
