You're right, that script doesn't work anymore. I needed to install it anyways, so I'll tell you how I did it.

First, get the rp8_linux20_libc6_i386_cs2_rpm file from the real.com website. Don't change the name and remember where it's located.

Then get THIS file. Install this deb file and it will ask you where the file above is located. Tell it, and then it'll be installed. Sorry about pointing you to an out-dated script before.
