Thank you thanos1983 and thechartist for your responses. I'll try both and inform here result.

Updating curl and ca-certs might take some time as I don't have root on this box but I'll get an admin to do it.

thechartist can you please give me some instructions on how you did it from git? I did git clone https://github.com/gugod/App-perlbrew.git It created App-perlbrew directory under my home directory. But then perlbrew init is failing with `-bash: perlbrew: command not found`

I tried running perlbrew init from my home directory as well as after doing cd App-perlbrew It gives same error: command not found
