Installing REV in Linux - how?

[Barry Levine]

I DL'd the v2.0.3 Rev but the .tgz file (when I double-click it to open 
it in KDE) appears to be missing much of what needs to be there; the 
"engines" folder is empty, for example. I'm running YDL (Yellow Dog 
Linux) on my PowerBook.

Taking into account I'm a Mac guy (obvious by my eMail) who expects a 
"drag & drop" installation, what am I doing wrong?

Thanks,
Barry
