The issue is that helping you with this would require writing an introductory Linux tutorial and, while I'd like to help, I don't have the time for it. But here's an abbreviated version that I hope points you in the direction of self-education.

You should be able to download compiled versions of the programs from the trifinite site's download area as .tgz files.

Then you'll need to decompress the files.

If you downloaded to your 770, you'll decompress them using tar--a search for "tar" on this site may point you to an explanation. However, this requires a slightly involved process on the 770 to allow you to become the "root" user.

I recommend you download to a PC or Mac and decompress the tgz files with zip or rar, and then use USB to transfer them to the 770.

You're almost there. On the 770, load Application Manager, use the Install from File option in the menu to install the file. Done.
