Yes. The "shebang" line
#!/usr/bin/env perl6
means "use the env to find the perl6 exe and run it" just as:
#!/usr/local/bin/perl6
does, only that's more specific. So, you're seeing P6 in interactive mode, and
it's advising you that w/o Linenoise or Readline, you won't be able to use "<up
arrow>" etc for editing in interactive mode.
$ man env
NAME
env - run a program in a modified environment
You can do
$ which perl6
to see where the exe might be found, too.

Subject: env?
Hi All,
Fedora 13 (Linux)
rakudo-pkg-Fedora31-2019.07.1-03.x86_64.rpm
At the top of all my Perl 6 programs, I place
#!/usr/bin/env perl6
So I decided to run env by itself and see what I got:
$ /usr/bin/env perl6
You may want to `zef install Readline` or `zef install
Linenoise` or use rlwrap for a line editor
To exit type 'exit' or '^D'
Is this suppose to happen?
Many thanks,
-T
