151046 clang-16 package missing gcc dependency

I have a system based on 151046 (heliosv2) and was trying to install the clang package to test something. After installation a basic C and C++ program failed to build in similar ways with:

rm@beowulf:~$ clang++ -std=c++11 tst.cpp

I received a hint to install the gcc-12 package from @citrus-it which did fix it. I suspect this clang package (and possibly others) are missing a dependency upon which to get the gcc crt and standard library files.
