Do you have the hd library installed?

In my $PDK_ROOT I only have sky130A In PDK_ROOT/skywater-pdk/libraries, I have a directory for - sky130_fd_sc_hd

During what stage do you see those?

Thanks, it's in stage 36 - magic spice export -

After these there are thousands of these warnings for many library cells.
