How can I use a new Perl module without install permissions?

Download package form CPAN to a folder:

wget http://search.cpan.org/CPAN/authors/id/S/SZ/SZABGAB/Parallel-ForkManager-1.06.tar.gz
gunzip Parallel-ForkManager-1.06.tar.gz
tar -xvf Parallel-ForkManager-1.06.tar

before this create a folder in home to store your local modules, now go into downloaded folder and run follwing cmmands:

perl Makefile.PL PREFIX=/home/username/myModules
make
make test
make install

get the path to ForkManager from the installed folder,/home/username/myModules and locate Parallel folder and get the full path to this.

Now in your perl file put these at the beggining

use lib '/home/username/myModules/bin.../Parallel';
use parallel::ForkManager;

--That should do it.

From perlfaq8: How do I keep my own module/library directory?:

When you build modules, tell Perl where to install the modules.

For C-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For C-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuild_arg --install_base /mydir/perl
cpan> o conf commit

INSTALL_BASE tells these tools to put your modules into F. See L for details on how to run your newly installed moudles.

There is one caveat with INSTALL_BASE, though, since it acts differently than the PREFIX and LIB settings that older versions of ExtUtils::MakeMaker advocated. INSTALL_BASE does not support installing modules for multiple versions of Perl or different architectures under the same directory. You should consider if you really want that , and if you do, use the older PREFIX and LIB settings. See the ExtUtils::Makemaker documentation for more details.

Check out this post from Mark Dominus

Excerpt:

• Set PREFIX=X when building the Makefile
• Set INSTALLDIRS=vendor and VENDORPREFIX=X when building the Makefile
  • Or maybe instead of VENDORPREFIX you need to set INSTALLVENDORLIB or something
  • Or maybe instead of setting them while building the Makefile you need to set them while running the make install target
• Set LIB=X/lib when building the Makefile
• Use PAR
• Use local::lib

Mark also gives another solution in his blog which takes a bit more space to desribe but boils down to running make and make test but not make install and then using the stuff in blib/.
