I recently upgraded my macOS GNAT from 2015 to Simon's latest offering ("if=
 it ain't broke...") on new Apple hardware. At the same time I used Apple's=
 Migration Assistant to transfer files. From Visual Studio Code, I use a sh=
ort shell script to run gprbuild. This has worked flawlessly for quite a wh=
ile. Now things are broken and I can't figure out what is wrong even after =
reviewing the gprbuild docs.

GPRBUILD 23.0.0 (20221109) (aarch64-apple-darwin21)

Here is the shell line invoking gprbuild
gprbuild -p /Users/me/Documents/Programs/Ada/Code/My_Projects/TextMate_Samp=
ling/build.gpr

Here is the gpr file named build.gpr after deleting a bunch of comments  (s=
orry for the length);
with "MPFR_Library"; -- Multiple precision floating point ops and functions
with "GMP_Library";  -- Multiple precision integer ops and functions
with "Octave_Library"; -- Octave built-in functions (not the loadable funct=
ions from Octave)
with "GSL_Library"; -- GNU Scientific Library, installed as part of Mac Por=
ts.

Here is the path to the main program. The path is in the sources list in bu=
ild.gpr.
/Users/me/Documents/Programs/Ada/Code/My_Code/Specialized/Radar/Uniform_Ape=
rture_Sum.adb

And here is the complaint from GNAT when I try to build:
build.gpr:61:19: "Uniform_Aperture_Sum.adb" is not a source of project "bui=
ld"
