mac - No such file / Architecture issue on #include <sodium.h>

[rkytopen]

Hello-
I am currently upgrading from an Intel-based Catalina system to an M1-based Monterey system, and I'm now receiving the following when trying to run a previously-working script:

‘/usr/local/opt/libsodium/lib/libsodium.23.dylib’ (no such file),
‘/usr/local/lib/libsodium.23.dylib’ (mach-o file, but is an incompatible architecture (have ‘arm64’, need ‘x86_64’)),
‘/usr/lib/libsodium.23.dylib’ (no such file)

Any advice? My first install passed the make check with no errors, reinstalling generated the attached error log.
test-suite.log

On M1 systems, Homebrew installs software in /opt/homebrew not /usr/local any more.
