Gnupg build tries to use with makeinfo an option which is not know/supported
by the in FreeBSD-11.3-STABLE.

The ports kit needs to be either modified to avoid the unsupported option or
makeinfo in FreeBSD-11.3-STABLE needs to be updated to support it.

The unsupported option is '--css-ref=/share/site.css'.
See an example below...


rm -rf $backupdir; exit $rc
incd="`test -f defsincdate || echo './'`defsincdate"; \
for file in gnupg7.texi gpg.texi gpgsm.texi gpg-agent.texi dirmngr.texi scdaemon.texi tools.texi wks.texi ; do \
              /usr/local/bin/yat2m -I . --release "GnuPG 2.2.19" --source "GNU Privacy Guard 2.2" --store \
                  --date "`cat $incd 2>/dev/null`" \
          `test -f '$file' || echo './'`$file ; done
