audiocd: mp3 compiled but not available ?

[Pavel Troller]

Hi!
  I have a problem in my new 3.3.0 installation (3_3_BRANCH), that audiocd
ioslave can't work with mp3.
  The lame encoder plugin is compiled in:
root at arcus:/usr/src/kde3/kdemultimedia/kioslave/audiocd/plugins# l /opt/kde3.3/lib/kde3/libaudiocd_encoder_*
-rwxr-xr-x  1 root root  1794 Aug 30 07:26 /opt/kde3.3/lib/kde3/libaudiocd_encoder_flac.la
-rwxr-xr-x  1 root root 15912 Aug 30 07:26 /opt/kde3.3/lib/kde3/libaudiocd_encoder_flac.so
-rwxr-xr-x  1 root root  1768 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_lame.la
-rwxr-xr-x  1 root root 68728 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_lame.so
-rwxr-xr-x  1 root root  1864 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_vorbis.la
-rwxr-xr-x  1 root root 49348 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_vorbis.so
-rwxr-xr-x  1 root root  1762 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_wav.la
-rwxr-xr-x  1 root root 10840 Aug 30 07:25 /opt/kde3.3/lib/kde3/libaudiocd_encoder_wav.so
  But neither mp3 folder of the CD nor lame settings in the kcm module are available.
  Any hint, what I should check ?
