While I'm sure its something I've done wrong, I can't seem to find it. I'm using bindgen = "0.55.1" and trying to generate pjsip bindings, although the problem seems to be well before that. This is the output from the build:
error: failed to run custom build command for `test-pjsip v0.1.0 (/Users/bruce/Projects/rust/examples/test-pjsip)`

I installed clang, via the bindgen recommendation of brew install llvm on macOS. I've verified that /usr/local/opt/llvm@11/lib/libclang.dylib does exist. I suspect that the symbol not existing is the issue. Should I be installing a different (older) version of clang, and if so, what version?
