sscan R2-11-4 build error on macOS Sonoma?

["J. Lewis Muir via Tech-talk" <tech-talk at aps.anl.gov>]

Hello, Tech-Talkers!

I'm building synApps 6.2.1 against EPICS Base 7.0.7 on macOS Sonoma
(14.1.1) on Apple Silicon (EPICS_HOST_ARCH=darwin-aarch64), and the
build fails with an error while building sscan; the end of the build
output is below.  I'll keep looking into the issue, but since it's not
immediately obvious to me what's wrong, I thought I'd ask here, has
anyone successfully built sscan on this platform?

Thanks!

Lewis
