Awfully sorry, I don't hang out in the forum as much as I should (because I hang out in the game probably more than I should

Anyway, the answer to your question is yes, DJL can handle all prerequisites and install all missing libraries automatically. I am running Auteria on Linux x86-64 and had no problem with any libraries. In fact what DJL does in automatic mode (the default if I remember correctly) is run the game, check if it fails due to a missing library, install that and try again for as long as it takes to get all missing libraries.
There is also a library repository, so you can install libraries manually, either if you know which ones you need, or by monitoring program output and checking what library it is missing. But the best thing is to leave it in auto mode and just let it do its thing

I recommend it to anyone wishing to install Auteria on Linux (either 32 or 64 bit.)
And I should also say that DJL is also a great way to browse through a list of Linux games complete with a description, screenshot and other info such as genre, platform, current version and a link to the project's homepage. After all, that's how I found Auteria in the first place! It will also handle updates to installed games, though not automatically.
