LinuxQuestions.org - why doesn't lame work in K3B?

In http://www.linuxquestions.org/questi...s-user-799953/ , someone showed me how to use lame to convert wav files to mp3. When using K3B sometime later, I noticed that mp3 was now listed as an option for the formats I could rip CD tracks in. I'm pretty sure it was never in the list before, and it says not just "mp3" but "mp3 (lame)" so it is obvious that my installing lame made mp3 an option in this list.

The thing is, it doesn't work. I've tried burning in mp3 now, and every time, some error prevents it. The debugging output says:

System
-----------------------
K3b Version: 1.0.5

KDE Version: 3.5.10
QT Version: 3.3.8b
Kernel: 2.6.27-1-mepis
Devices
-----------------------
ATAPI CD-RW 52X24 K.JC (/dev/sr0, ) [CD-R, CD-RW, CD-ROM] [CD-ROM, CD-R, CD-RW] [SAO, TAO, RAW, SAO/R96P, SAO/R96R, RAW/R16, RAW/R96P, RAW/R96R]

and the error message, showing the command that failed, is shown in this screenshot I attached. (It wouldn't let me copy the text to the clipboard.)

Any idea why it doesn't work? If I could rip tracks as MP3 in K3B, I could rip them all at once, and it would be much faster than using the lame command on each file in a terminal window.
