Yes, plplot build-depends on gnat and gnat-14. The package FTBFS with 
gcc-15 because it automatically disables the ADA binding build. The 
Ada/CMakeFiles/CMakeError.log file contains the following error message:

     Building Ada object CMakeFiles/testadacompiler.dir/testadacompiler.o
     /usr/bin/gcc    -g -O2 -ffile-prefix-map=/var/data/rlaboiss/debian/PKGS/plplot/plplot=. -fstack-protector-strong -fstack-clash-protection -fcf-protection  -gno-record-gcc-switches  -o CMakeFiles/testadacompiler.dir/testadacompiler.o -c /var/data/rlaboiss/debian/PKGS/plplot/plplot/obj-x86_64-linux-gnu/language_tests/Ada/CMakeFiles/CMakeTmp/testadacompiler.adb
     gcc: fatal error: cannot execute ‘gnat1’: posix_spawnp: No such file or directory

I am Cc'ing this message to Ludovic Brenta and Nicolas Boulenguez, the 
maintainers of the gnat package, who might be able to help us with 
the issue.

Best,
