How can I use a new Perl module without install permissions?
Solution 1
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.
Solution 2
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.

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/.
Solution 4
There's the PERL5LIB environment variable, and -I
on the command line when it comes to using the module. There are mechanisms for telling CPAN and CPANPLUS.
There is information in question 5 of the CPAN manual (perldoc CPAN, or look at CPAN itself).
Solution 5
use lib 'directory';
use Parallel::ForkManager;

Here is my situation: I know almost nothing about Perl but it is the only language available on a porting machine. I only have permissions to write in my local work area and not the Perl install location. I need to use the Parallel::ForkManager Perl module from CPAN
How do I use this Parallel::ForkManager without doing a central install? Is there an environment variable that I can set so it is located?
Thanks

Schwern over 15 yearsThere's no reason to mess with vendor stuff. You should leave INSTALLDIRS as it is, "site" is correct for locally installed modules. And use INSTALL_BASE, not PREFIX/LIB.
