  1. Yes, %INC contains the full path a module was loaded from.

    Example:

    $ perl -M'Data::Dump qw(pp)' -e 'pp(\%INC)' {   'Data/Dump.pm'         => '/usr/share/perl5/Data/Dump.pm',   'Exporter.pm'          => '/usr/share/perl/5.10/Exporter.pm',   'List/Util.pm'         => '/usr/lib/perl/5.10/List/Util.pm',   'Scalar/Util.pm'       => '/usr/lib/perl/5.10/Scalar/Util.pm',   'XSLoader.pm'          => '/usr/lib/perl/5.10/XSLoader.pm',   'overload.pm'          => '/usr/share/perl/5.10/overload.pm',   'strict.pm'            => '/usr/share/perl/5.10/strict.pm',   'vars.pm'              => '/usr/share/perl/5.10/vars.pm',   'warnings.pm'          => '/usr/share/perl/5.10/warnings.pm',   'warnings/register.pm' => '/usr/share/perl/5.10/warnings/register.pm', }
