>BTW I still have a version of perl installed??

 But is it the /OS/ version of PERL -- or one that was installed into an
alternate location that the system does not reference.

 What does
  which perl
display? Mine shows /usr/bin/perl.

 On a recent Beaglebone I installed the vim-gtk3 package... That's a
package that provides the vim editor along with gvim (graphical interface)
version...

 It sucked in half a doze /ruby/ related packages!

debian@beaglebone:~$ sudo apt-install vim-gtk3get
Reading package lists... Done
Building dependency tree
Reading state information... Done

The following additional packages will be installed:
  fonts-lato liblua5.2-0 libruby2.3 libyaml-0-2 rake ruby ruby-did-you-mean
ruby-minitest ruby-net-telnet ruby-power-assert ruby-test-unit ruby2.3
rubygems-integration vim-gui-common zip

 And if they require certain packages, like PERL, then that PERL will be
reinstalled with them.

 For normal package manager installs, there will only be ONE version of
anything. They normally don't install multiple versions (well, Python
typically has a 2.x and 3.x version -- with the OS normally using just one
of them, and users have to specify the other

 Note how "python" is a link to "python2" and that itself is a link to
"python2.7".

pi@raspberrypi:~$ ls -l /usr/bin/perl*
-rwxr-xr-x 2 root root 2844532 Mar 31 07:51 /usr/bin/perl

-rwxr-xr-x 1 root root    5632 Mar 31 07:51
/usr/bin/perl5.28-arm-linux-gnueabihf

 Interestingly, they didn't link perl to perl5.28.1even though they are
identical.
