Required Modules: VUser-Google-Apps requires the following Perl modules that are not included with Perl: - VUser::Google::ProvisioningAPI Other vuser extensions may require other Perl modules. Please see the documentation included with those extensions for additional requirements. Basic Installation: perl Makefile.PL make make test make install That will install vuser on your system in /usr (or /usr/local) by default. You can define a different install path by setting PREFIX when running Makefile.PL. For example, to install vuser in your home directory perl Makefile.PL PREFIX=~ or to install in /opt perl Makefile.PL PREFIX=/opt The install script will create lib, share and sbin directories in PREFIX. If you install in a PREFIX that is not included in perl's default library paths, you will need to set PERL5LIB to include the new directory. For example, if you set PREFIX=/opt, you might add this to your .profile (or /etc/profile). export PERL5LIB=/opt/lib/perl5/site_perl/
