It seems to me that perlbrew might meet your needs. If I understand your requirement, the following link should give you an idea of how to go about this.

Managing Perl environments with perlbrew

My understanding is that each version of Perl installed is isolated. And locating it can be accomplished by:

If you need to install perlbrew somewhere other than your home directory, just download the installer and pass it the PERLBREW_ROOT environment variable.

never used it but Perl::Build may be what you are looking for. Specifically:

Perl::Build->install_from_cpan($version, %args)

Install $version perl from CPAN. This method fetches tar ball from CPAN, build, and install it.

You can pass following options in %args.

    dst_path

    Destination directory to install perl.

Now, I suspect it may be one thing to handle many perls on the command-line, for a user, via plenv or perlbrew and a different thing to tell your webserver which perl to use etc.

I would recommend using perl-build, which provides an easy way to install perl in an arbitrary directory.

There are ways to lock down subdirectories from being served by a web server. Even so, putting the executable for a general-purpose programming language within your document root seems like a terrible idea. Since you're not talking about a PSGI server as part of this scenario and talking about needing to put things in a particular directory, it seems you're likely using CGI.

Imagine you have CGI enabled within your web root. Now imagine for some reason the subdirectory containing perl within that web root becomes web accessible. The HTTP verb POST sends the request body from the client to the web server, which then runs the executable mapped at the requested URI. The request body is then passed in its entirety to that executable's STDIN. Eve fuzzes and futzes and finds your perl executable. She then POSTs arbitrary code, which then runs. Suddenly your system is a command and control system for a botnet or something even worse.

I believe perl-build might be the right answer. It is already integrated in plenv and a plugin but only with plenv install.

I should have described my environment better. The web server is running in a different server and for security reasons home directories are not mounted. Whereas the web page directories are mounted to the system in which I use shell. Besides this, the web server is running a seriously limited OS and could be updated not in sync with the other system, including Perl versions. So I need to have everything the software needs in the disk with the web page.

Perhaps update the OP with your refined requirements so that those who don't read all the way down to this post first will not waste effort pursuing snipe. Please see How do I change/delete my post?

Installing Perl is as east as following these steps:

wget https://cpan.metacpan.org/authors/id/X/XS/XSAWYERX/perl-5.28.0.ta
+r.gz
tar xvzf perl-5.28.0.tar.gz
cd perl-5.28.0
sh Configure -des -Dusethreads -Dprefix="$HOME/public_html/prog"
make
make test
make install

The instructions on how to install Perl are found in the file named INSTALL. (e.g. [https://metacpan.org/source/XSAWYERX/perl-5.28.0/INSTALL|5.28.0's
