Install

If the @INC directory not specified via the environment variable, cpan fails cannot configuring the installed module, this seem to affect the dependency resolution:

PERL5LIB=/home/regular/perl/lib/perl5 \
  cpan -T \
    Crypt::OpenSSL::Guess \
    Crypt::OpenSSL::AES \

eumm.md

ExtUtils-MakeMaker

Options for EUMM can be permanently set in PERL_MB_OPT environment variable.

ll.md

local-lib

https://metacpan.org/pod/local::lib

# Install LWP and its missing dependencies to the '~/perl5' directory
perl -MCPAN -Mlocal::lib -e 'CPAN::install(LWP)'
 
# Just print out useful shell commands
$ perl -Mlocal::lib
PERL_MB_OPT='--install_base /home/username/perl5'; export PERL_MB_OPT;
PERL_MM_OPT='INSTALL_BASE=/home/username/perl5'; export PERL_MM_OPT;
PERL5LIB="/home/username/perl5/lib/perl5"; export PERL5LIB;
PATH="/home/username/perl5/bin:$PATH"; export PATH;

mb.md

Module-Build

Options for MB can be permanently set in PERL_MM_OPT environment variable.

perl Build.PL --install_base /home/regular/perl

perl.md

Perl

Library directory for Perl can be permanently set in PERL5LIB environment variable.

Calling the script:

perl -I/home/regular/perl/lib/perl5 /home/regular/perl/bin/perltidy --version

Note that -I (@INC) won't understand ~ because it's concatenated to it (and therefore can't be expanded by the shell).
