# Install Perl modules in macOS system Perl without cluttering /usr/local

# Prerequisite
xcode-select --install

# Install modules locally, instructing cpanm to build Universal Binaries
sysperl=/usr/bin/perl
curl -L https://cpanmin.us/ | \
    ARCHFLAGS='-arch arm64 -arch arm64e -arch x86_64' \
    $sysperl - -n --local-lib=~/.sys_perl5 \
    JSON::Parse https://github.com/LiosK/Finance--Quote--YahooJapan.git

# NOTE: persist these env vars to have sysperl and FQ load local libs and YahooJapan
export PERL5LIB="$HOME/.sys_perl5/lib/perl5"
export FQ_LOAD_QUOTELET='-defaults YahooJapan'

# Test
$sysperl -e 'print "$_\n" for @INC;'
$sysperl ~/.sys_perl5/bin/fetch_quotes_from_yahoo_japan.pl

Motivations:

• Modules need to be installed in system Perl to be loaded on GUI apps
• cpan --sudo module_name puts some script and document files under /usr/local, which conflict with Homebrew Perl
