You seem to assume that Ubuntu and FreeBSD both have the same version of
Ruby installed. The current version in FreeBSD is 2.4.3. 2.3 is still
available as lang/ruby23, but should only be used when some code won't work
with 2.4. The Ubuntu system is still running 2.3. Have you checked for
available upgrades?
On FreeBSD you can get the current version of an installed package with the
command "pkg info -E ruby". The trailing ",1" indicates that at some point
ruby was rolled back for some reason, but it is not really a part of the
version number.
