in reply to What modules required
Well, IO::Socket and strict are standard, so that should "just work" if your perl is properly installed.
The other three:
are some local files. Without further information it's hard to say, but you should look for a directory CONFIG_ROOT containing the file general-functions.pl. Presumably that will contain the variable $General::swroot that is required to generate the other file names. If nothing else, run the script from the directory containg the CONFIG_ROOT directory to at least get an idea of whether it will work or no.
But I'm really just speculating. With custom code you really need to find the author or maintainer. In a public forum like this, you have to provide lots more detail.
