The file /usr/local/etc/rc.d/fusefs is missing. Therefore ntfs-3g does not work. The port fusefs-kmod contains an usable script.in: %%KMODDIR%% -> /boot/kernel/
Describe "does not work". What command are you running, and what is the error message?
Now, with FreeBSD 11.2, the ntfs-3g works without start-stop-script.
I'm closing this bug then. Reopen if it recurs on any supported release.
