This error has come up before a few times over the past couple years,
always when installing the control package, and only on macOS systems.

The "<built-in>" tag is coming from the gfortran compiler itself. I
suspect it is referring to built-in Fortran functions.

The control package is one of the few Octave Forge packages that has
Fortran source code that is compiled by the pkg command when installed.

Here are some references to threads and bug reports where this has come
up before, maybe this will help you resolve this or help users fix it
when it comes up again.
