The out-of-the-box solution is to have per-application module bundles, or perl installs. So each application which requires many and potentially incompatible prerequisites, gets its own local::lib, its simple

$ENV{PERL_MM_USE_DEFAULT}=1;
$ENV{PERL_MB_OPT}='--install_base /some/path/appxyzv23/perl5';
$ENV{PERL_MM_OPT}='INSTALL_BASE=/some/path/appxyzv23/perl5';

use strict;
use warnings;
use CPAN;

CPAN::Shell->install(qw[
AUTHOR/Module-1.23.tar.gz
... 
]);

...
use lib '/some/path/appxyzv23/perl5';

There is also only - Load specific module versions; Install many
