Tumorcode installation on macOS

Hello,

I'm trying to install tumorcode on my macOS machine (Catalina 10.15.6) using Spack. I'm new in Spack but I succeed the installation and it is working. 

Now I've to install tumorcode but I do not understand how can I complete the package.py script in order to succeed with the installation. Do you have any suggestion?

Thank you in advance.

Best,
Gabriele
