Look at the source of the Makefile.PL and/or ExtUtils::MakeMaker or Module::Install, depending on what the Makefile.PL actually uses.

Also take a look at local::lib.

Consult the manual :) ExtUtils::MakeMaker

Are they all still in use?

Yup

Is there others?

Well, Build.PL/Module::Build takes different arguments, then there are convenience tools like local::lib and perlbrew.

local::lib site:perlmonks.org perlbrew site:perlmonks.org Makefile.PL PREFIX site:perlmonks.org Build.PL PREFIX site:perlmonks.org

There are numerous articles that come up, say, on a Google search of “Perl non root,” and these would be the best place to start.

I freely admit that it is “somewhat voodoo.”   Techniques have evolved over time so you should look only at fairly-recent articles.   This is, shall we say, “a place where ‘TMTOWTDI’ is not necessarily such a wonderful thing.”   But once you get the magickal spells just right, it works very well indeed.

Anytime I install a Perl-based web site, for instance, and for public or internal-only use, I always set up the virtual-host so that the CPAN modules that I need to use are fetched only from a site-specific local library of my choosing.   Web hosting companies apply software updates too, and any unrecognized dependencies can break a site.   This practice greatly reduces such concerns.

I am trying to install Sort::Key::Multi . It seems to be found. However, it calls Sort::Key which then says Can't locate loadable object for module Sort::Key in @INC I have been trying Makfile.PL PREFIX=/MyDir and in the perl script usr lib "/MyDir" Also tried perl -I /MyDir I must be missing something here. Just forgot them, I did usr /MyDir

/MyDir is absolute (on nix), but MyDir is relative path, they are not the same
