Created attachment 227771 [details] groff moved to ports The GNU roff toolchain has been removed from base, see /usr/src/UPDATING entry 20170531. sgmlformat relies on "groff" command to be in PATH and installs three .ts files with references to /usr/share/tmac that does not exist in modern FreeBSD versions. Attached path adds textproc/groff to RUN_DEPENDS and fixes broken references.
Fixed with https://cgit.freebsd.org/ports/commit/?id=db8499a9f8877367b68db78a02c8bf9bf312d572 Sorry, forgot to add PR: to the commit log.
