>Description:
After adding gfortran to PATH, switching to bsdtar, finally I can use octave-forge! only, the most basic package:

octave:1> pkg install -forge control
...
/home/fly/octave/control-3.0.0/x86_64--netbsd-api-v51/__control_slicot_functions__.oct: failed to load: /home/fly/octave/control-3.0.0/x86_64--netbsd-api-v51/__control_slicot_functions__.oct: Undefined PLT symbol "dlatzm_" (symnum = 204)

Many packages require control, and control uses SLICOT.
SLICOT uses a deprecated function: dlatzm.

SLICOT can be patched (for example: https://trac.macports.org/ticket/49824 ), but we have no way to do so if we have no octave-packages, and just use upstream as-is.
>How-To-Repeat:

>Fix:
No idea, but it claims if I just add BUILD_DEPRECATED = Yes to make.inc it will build. didn't work?
