Here's how I've done it in my Mac ...
Placed all my *.mp3 files to a folder, and open Terminal to that folder .. making sure my mp3 files are in correct sequence audio1.mp3 audio2.mp3 and so on ...
cat *.mp3 > Bookname.mp3
Then I went to Itune and added that big MP3 file to my Library (Add to Library :))
When the Bookname.mp3 shows up under my Music, I right click on it, Get Info, Option and change the Music type to "AudioBook" type ...
That's it ..
