Hi Justin,
Thanks for those suggestions!!
I've made a few changes to my configure.sh file (including deleting the chaco line, which was also causing problems - I removed the appropriate install in the corresponding folder in externalpackages/chaco - but I've since added the chaco line back in). As you suggested, I split up the options on three lines.
Now, different errors are coming up when I run ./configure.sh

But, I did install petsc without any issues:

I installed 3.17-mac-silicon.sh. However, it doesn't look like there's an "include" directory"
I've attached the updated configure.sh file
All the best,
Anna
