Installing Perl5 Modules Locally
Normally, the Perl5 module installation procedure includes commands something like these:
% perl5 Makefile.PL% make% make test% make install% make clean
The first command, perl5 Makefile.PL, directs perl5 to create a makefile for the new module you are installing. When installing a perl5 module locally you must designate the home directory of your perl5 installation on the command line. That information is used by perl5 to create the makefile. Substitute the following command for perl5 Makefile.PL:
% perl5 Makefile.PL PREFIX=/usr/home/USERNAME/usr/local
The value USERNAME above should be replaced with your Virtual Private Server primary user account name. So the complete installation process is:
% perl5 Makefile.PL PREFIX=/usr/home/USERNAME/usr/local% make% make test% make install% make clean
For older modules it may be necessary to designate several other variables on the command line during the module installation:
% perl5 Makefile.PL PREFIX=/usr/home/USERNAME/usr/local \ INSTALLPRIVLIB=/usr/home/USERNAME/usr/local/lib/perl5 \ INSTALLSCRIPT=/usr/home/USERNAME/usr/local/bin \ INSTALLSITELIB=/usr/home/USERNAME/usr/local/lib/perl5/site_perl \ INSTALLBIN=/usr/home/USERNAME/usr/local/bin \ INSTALLMAN1DIR=/usr/home/USERNAME/usr/local/lib/perl5/man \ INSTALLMAN3DIR=/usr/home/USERNAME/usr/local/lib/perl5/man/man3
To save yourself some typing you can create a file and put these variable assignments above in to a file (FILENAME) something like this:
PREFIX=/usr/home/USERNAME/usr/local \ INSTALLPRIVLIB=/usr/home/USERNAME/usr/local/lib/perl5 \ INSTALLSCRIPT=/usr/home/USERNAME/usr/local/bin \ INSTALLSITELIB=/usr/home/USERNAME/usr/local/lib/perl5/site_perl \ INSTALLBIN=/usr/home/USERNAME/usr/local/bin \ INSTALLMAN1DIR=/usr/home/USERNAME/usr/local/lib/perl5/man \ INSTALLMAN3DIR=/usr/home/USERNAME/usr/local/lib/perl5/man/man3
Then, each time you install a perl5 module you can use the following syntax:
% perl5 Makefile.PL `cat FILENAME`% make% make test% make install% make clean
You also can have a few different local module installation procedures, for example one for production perl and another for development:
% perl5 Makefile.PL `cat FILENAME.production`
or
% perl5 Makefile.PL `cat FILENAME.development`
)
