I build groff on MacOS 11 (intel) and get the following message:

troff: backtrace: file 'man/groff_char.7':1000
troff:man/groff_char.7:1000: warning: can't find special character '.j'

troff: backtrace: file 'man/groff_char.7':1839

This is with bootstrap, configure, make.

I have Ghostscript 9.55.0 installed.
Do I need a more recent version for these characters?
