make: stopped in /usr/ports/security/py-cryptography

I am not sure what to make of this port build failure. I suspect that you are including: rustc: 1.74.1 (a28077b28 2023-12-04) (built from a source tarball)
has something to do with it.

I am not sure why some ports are inclined to bundle ports like rust when they that port is already installed. Seems to me that the bundled version conflicts with the installed version and causes errors.

The entire error msgs:
