Did so, but…

Installing fusefs-ext4fuse-0.1.3_1,1...
Please note that that this port only supports ext4 in read-only mode.
You might want to consider using sysutils/fusefs-ext2 which supports
ext2, ext3 and ext4 with read write support.
===>   NOTICE:

This port is deprecated; you may wish to reconsider installing it:

Please consider using sysutils/fusefs-ext2 as upstream development is stalled.  Contrary to what its name suggests it supports ext2, ext3, ext4 in read/write  mode..

It is scheduled to be removed on or after 2019-12-01.

and later…:
