You need to apply the 22 years worth of problem-solving skills that you've acquired to learning new things.
Your problem isn't "right out of the box" it's more like "wrong kind of box". You don't have a Windows based computer anymore. The paradigm has changed completely.
It is possible that you already have perl installed - it comes loaded on many versions of Solaris.
Try opening a shell window & typing:
If you get any kind of response other than an error - it's already there.
If not, then you have to find out if you are also the System Administrator for your system as well as the user. If not, then you should ask the administrator to install it for you and to point you at some documentation to get you up to speed.
It doesn't seem right that someone should give you an entirely new platform that you're unprepared for and to make you the administrator also. It's a bit like dropping a fresh water fish in the ocean - nothing's going to work right and it's very dangerous.
Wait! This isn't a Parachute, this is a Backpack!
