You don't, unless you build it yourself.

That's the key value of open-source projects. You don't have to release a binary, just source code and a build guide. It's also one of the reasons why I have such high respect for OS distributions like BSDs and Slackware. They give you a good base that you can build upon if you know what you're doing.

The problem is, many PC users don't really know what they're doing.

Can't tell you how many times I've had to explain how environmental variables work to developers, and that's a pretty simple concept compared to many other things in an operating system.

Most people cut their teeth on Windows, where the system environment bars are just a basically a section of the registry.
