I presume there is a precedence/timing issue,
if the package is not loaded, I have the warning
octave:4> __all_opts__ ("residmin_stat");
octave:5> pkg unload optim
octave:6> __all_opts__ ("residmin_stat");
warning: optimset: no defaults for function `residmin_stat'
so I can ignore the warning when installing
