Thanks.  Here's the important bit:

So the linker cannot find the libgccjit library.  Do you have it, and
if so, is it installed in the directory where the linker looks for
libraries, for example where you have libpng16, libcairo, and others.

IOW, it sounds like your libgccjit installation is incomplete for some
reason.
