Thanks for your really brave efforts
You can install the Perl modules like this:
(where Some::Module is the name of the missing module)
perl -MCPAN -e 'install Some::Module'
In your case, currently, it is Proc::ProcessTable, so the command will be:
If you have not installed Perl modules using cpan earlier, you will come across an interactive session wherein you will be asked a few simple questions. Once you answer these questions, cpan will download the required module and install it on your system.
perl -MCPAN -e 'install Proc::ProcessTable'
After Proc::ProcessTable is installed, you should try to run the script again when, if any other module is missing, it will show a similar error as you got - with the name of missing module.
Once all modules are installed, this script should run.
EDIT: To check if the module exists, do this:
If it gives out nothing. The module exists.
perl -e 'use Some::Module'
If the module does not exist, it will give out the same kind of error, you got above.
All the best and thanks,
