The error in the log is:

error: use of undeclared identifier '__sanitizer_XDR'; did you mean '__sanitizer'?

clang-11-bootstrap needs to be blocked from building on this system:

macOS 14.2.1 (darwin/23.2.0) arch arm

and things set up so it is never brought forth as a dependency.

It is completely unnecessary, of course, on such a system and more to the point, we don't want to waste time trying to make this old version of clang, useful only for bootstrapping older systems, work on every new system.

If so, then how do you explain the existing dependencies:

➜  ~ git:(adf) ✗  port info --pretty --fullname --depends clang-11-bootstrap
Full Name: clang-11-bootstrap @11.1.0+universal
Extract Dependencies: xz-bootstrap
Build Dependencies:   cmake-bootstrap, python27-bootstrap, diffutils-for-muniversal

➜  ~ git:(adf) ✗ port select --list python
Available versions for python:
	none
	python310
	python311 (active)

for python it's ok because I already use version 3.11, but in my case bootstrapping for cmake is a must

[kencu (Ken)]

if any deps exist on clang11-bootstrap on any newer systems (newer being any system where the systen clang is equal to or newer than clang11, say) , then they need to be removed.

Same issue reported for the clang-12 port in #69794.
