Attempting to modify ntpd/ntpdbase-opts.def and rebuild the resulting output files with Autogen 5.18.16 built from ports r2025Q4, I got an error message: cd ../../ntpd && env PATH=[...] AUTOGEN_DNE_DATE=-D autogen -L ../sntp/include -L ../sntp/ag-tpl --writable -DMAN_SECTION=1ntpdmdoc -Tagmdoc-cmd.tpl ntpd-opts.def Error in template /usr/local/share/autogen/cmd-doc.tlib, line 219 DEFINITIONS ERROR in /usr/local/share/autogen/cmd-doc.tlib line 219 for ntpd-opts.mdoc: Cannot locate converter for mdoc Failing Guile command: = = = = = (define sec-type (string-upcase (get "ds-type"))) (define sec-name (name-to-fname sec-type)) (define cvt-fn (find-file (string-append (get "ds-format" "man") "2mdoc"))) (if (not (defined?
