title: Unable to execute 'gcc-8': No such file or directory error: command 'gcc-8' failed with exit status 1. PySIT package installation
body: <p>I am trying to install a package called PySIT to be run with Python, and have followed the instructions on this install page (<a href="https://pysit.readthedocs.io/en/latest/install.html" rel="nofollow noreferrer">https://pysit.readthedocs.io/en/latest/install.html</a>) using pip on my terminal to install PySIT.</p>
  <p>I am using macOS Catalina for this, and have Anaconda installed on my computer.</p>
  <p>This is the output I get on my terminal when I run the command: python setup.py install</p>
  <blockquote>
  <p>gcc-8 -fno-strict-aliasing -I/Users/KBrindha/anaconda2/include -arch x86_64 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/KBrindha/anaconda2/lib/python2.7/site-packages/numpy/core/include -Ipysit/solvers/fd_tools -I/Users/KBrindha/anaconda2/include/python2.7 -c pysit/solvers/constant_density_acoustic/time/scalar/solvers_wrap.cxx -o build/temp.macosx-10.6-x86_64-2.7/pysit/solvers/constant_density_acoustic/time/scalar/solvers_wrap.o -O3 -fopenmp -ffast-math</p>

  <p>Any help on how to bypass this issue or install gcc-8 would be appreciated.
  For further information, I have Xcode and Xcode Command Line Tools installed in my computer.
  I also have &quot;just&quot; gcc (not gcc-8) installed at /usr/bin/gcc.</p>
