I think that means the operation is not supported.
In other word, No.
I've been happily using acls on my ext4 filesystems for some time. thus:
It ain't necessarily so (as Sporting Life would sing):
Perhaps you don't have permissions to /usr/local or /usr/local/test
Perhaps /usr/local/test is not a directory (-d -R would seem to require this)
Perhaps /usr/local is not ext4, or not mounted with acl enabled.
Suggestion: try something simpler first, like this
cd <some directory on an ext4 filesystem.* Your home directory, if possible.>
rm -f foo
setfacl -m u:bin:rx foo
Make sure that the output from df reflects an ext4 partition with acl enabled.
If that works, try more complicated things one at a time.* Setfacl can be a bit of a bear to get right.
