Got it, thanks, Dima.
I've been trying to jump through lots of hoops to get Sage to build and for
doctests to pass. Doctests are still not passing for me on OS X, in part
because of old previously reported problems (#40869, #40873), but I'm
seeing a new set of failures. Something is going wrong with text processing
and control sequences:

1 item had failures:
I'm also seeing failures like this after upgrading to OS X 26.2:
File "src/sage/misc/sagedoc.py", line 709, in sage.misc.sagedoc.format
Failed example:
cython('\n'.join(cython_code))
# needs sage.misc.cython
Expected nothing
Got:
ld: warning: building for macOS-15.0, but linking with dylib
'/Users/palmieri/Sage/TESTING/sage-10.9.beta1/local/lib/libec.14.dylib'
which was built for newer version 26.0
ld: warning: building for macOS-15.0, but linking with dylib
'/Users/palmieri/Sage/TESTING/sage-10.9.beta1/local/lib/libgsl.27.dylib'
which was built for newer version 26.0
We should be able to filter out warning messages like these, but I think we
should be able to set flags to specify which version of Mac OS we're
building for. Is MACOSX_DEPLOYMENT_TARGET being incorrectly set somewhere?
