Converting .ogg to mp3, Gstreamer not working

[seculor]

Hi I'm trying to convert some .ogg .mpa and .mpc files to .mp3 with a command like this:
gst-launch -v filesrc location=foo.ogg ! decodebin ! audioconvert ! lame ! id3v2mux ! filesink location=foo.mp3

But I'm getting the following error:
WARNING: erroneous pipeline: no element "lame"

I have lame and gstreamer installed:
rpm -qa|grep lame
lame-3.97-4.lvn6
lame-libs-3.97-4.lvn6
lame-libs-3.97-4.lvn6
twolame-0.3.10-1.lvn6
lame-3.97-4.lvn6

rpm -qa|grep gstreamer
gstreamer-plugins-base-0.10.11-1.fc6
gstreamer-tools-0.10.11-1.fc6
gstreamer08-plugins-0.8.12-7.fc6
gstreamer-plugins-base-0.10.11-1.fc6
gstreamer-plugins-good-0.10.4-3.fc6
gstreamer-0.10.11-1.fc6
gstreamer08-0.8.12-8.fc6
gstreamer-0.10.11-1.fc6

What could be the problem?

In FreeBSD, I use ogg123, included with vorbis-tools. I'm not sure if there's an rpm available. (In FreeBSD right now, Fedora's at work.)

To convert foo.ogg, I do
ogg123 -d wav -f foo.wav foo.ogg

Then, to convert it to mp3 I use bladenc. Again, I don't know if it's available as an rpm.

bladenc foo.wav

I realize this isn't an actual answer to your question but I hope it helps.

Yeah - just 'yum install vorbis-tools' and this includes ogg123.

Thanks for the replies. I have found a perfect solution - mplayer. Basically, what I was trying to do was to transfer my Amarok music collection to an RCA Lyra mp3 player using the dirtyxcode script. This way all the files are renamed properly according to the tag information stored in my Amarok collection.

This is how I solved the Gstreamer problem:
In the .kde/share/apps/amarok/scripts/dirtyxcoder-0.1/dirtyxcode file I replaced this line:
error=`gst-launch -p filesrc location="$file" ! decodebin ! audioconvert ! audioresample ! $encoder ! filesink location="$outfile" 2>&1`

with:
error=`mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader "$file" && lame -m s audiodump.wav -o "$outfile"`

Now I can just drag and drop any of my music tracks onto the device tab in Amarok and it automatically transcodes, renames, and copies them to the mp3 player.
