G'day areldy_exten,

Welcome to the Monastery.

I also have Perl 5.32.0 installed using Perlbrew. From the description of your setup, mine seems to be identical; of course, mine may differ from yours in areas that you haven't mentioned.

$ perlbrew list
 * perl-5.32.0
   perl-5.30.0

$ which perl
/home/ken/perl5/perlbrew/perls/perl-5.32.0/bin/perl

$ echo $PERLBREW_ROOT
/home/ken/perl5/perlbrew

$ $PERLBREW_ROOT/perls/perl-5.32.0/bin/perl -V

"Why isn't this included automatically in the @INC?"

Short answer: because it doesn't exist.

Longer answer. I've been using Perlbrew for a very long time, certainly more than a decade, and I don't recall $PERLBREW_ROOT/perls/<install-name>/lib/perl5 ever being a standard Perlbrew directory. This would be why such a path would not be automatically added to @INC.

I'm not a user of cpanm, I use cpan. As such, I'm not in any position to comment on your use of cpanm beyond suggesting that you check that you are using it correctly. I know cpanm is widely used: if you have questions about that, you can definitely get help about it here.

If you have modules installed in non-standard locations, consider using PERL5LIB (see "perlrun: ENVIRONMENT") or use the lib pragma. There are other ways of dealing with this but that's probably jumping the gun and heading off-topic for the current issue.

$ type perl
perl is /home/ken/perl5/perlbrew/perls/perl-5.32.0/bin/perl

"I've been using Perlbrew for a very long time, certainly more than a decade, and I don't recall $PERLBREW_ROOT/perls/<install-name>/lib/perl5 ever being a standard Perlbrew directory."

None of my perlbrew installations have such a directory either. And I do use cpanm.

Thank you kcott and tobyinky for the replies.

My purpose is to install a self-contained perl and a collection of modules all together.
Such that I can have my scripts work seamlessly by just pointing the shebang to the perl bin.
E.g.  $PERLBREW_ROOT/perls/perl-5.32.0/bin/perl in this case.

As I mentioned in my post I installed the modules by doing

cd $PERLBREW_ROOT/perls/perl-5.32.0
cpanm -L . MODULE
[download]

The cpanm is localed at $PERLBREW_ROOT/bin/cpanm
This has resulted in the following tree (truncated):

perls
\-- perl-5.32.0/
    |-- bin/
    |   |-- cpan*
    |   |-- perl*
    |   |-- perl5.32.0*
    |   \-- zipdetails*
    \-- lib/
        |-- 5.32.0/
        |   |-- AnyDBM_File.pm
        |   |-- App/
        |   |-- x86_64-linux-thread-multi-ld/
        |   \-- XSLoader.pm
        |-- perl5/
        |   |-- Alien/
        |   |-- alienfile.pm
        |   |-- x86_64-linux-thread-multi-ld/
        |   \-- XML/
        \-- site_perl/
            \-- 5.32.0/
[download]

As you can see it has created the perl5/ folder I mention.

Could you please suggest the correct way to install modules in this perl lib such that the module files sit in the given lib/5.32.0 or lib/site_perl area?

Thank you again!
