just a note...
after updating my 21.2 tree my rebuild failed with:
makeinfo -P xemacs -o ../info/xemacs.info xemacs/xemacs.texi
Making info file `../info/xemacs.info' from `xemacs/xemacs.texi'.
xemacs/programs.texi:1087: Unknown command `env'.
xemacs/programs.texi:1087: Misplaced {.
xemacs/programs.texi:1087: Misplaced }.
makeinfo: Removing output file `../info/xemacs.info' due to errors; use --force to
preserve.
found an old makeinfo (3.12) in my path, renamed and updated to the
texinfo-4.0 pkg, and all is happy
