Thanks for the reply. I did both suggestions. The mkfontdir commands executed but no joy on more fonts. The fc-cache command ran showed the results and stated that it had succeeded. However, no additional fonts are available in LibreOffice font selection.
Here's what I did:
Installed Freebsd 11.1 with no issues that I am aware of.
Installed x.org using pkg install with no problems
Installed gnome using pkg install with no reported issues
made config changes to have gnome start after boot with dbus enable, hald enable, gnome enable, gdm enable
Added urwfonts with the pkg install
Added FontPath for urwfonts to xorg.conf
When I do an fc-list I see a lot of fonts, but none of the ones I would like to see in LibreOffice (helvatica, times, gothic etc. do not show up.
I see liberation, droid, carlito, caleda and others I have never seen before.
I'm not sure what else to do.
