Playing mpc files on Raspbian (SqueezePlug)

Hi, I posted this at the RPi forums, but haven't had any luck there, so I thought I'd see if anyone here could help.

I've been running LMS (since Slimserver!) on my Ubuntu server, but thought it'd get another Pi to use instead to save some power.

Using Squeezeplug had made this a breeze, and though it's not as snappy as the Ubuntu server, particularly using the web interface, it's fast enough and MUCH smaller!

Anyway, I tried to play an album on my Squeezebox 3 that is in mpc format and it failed to play. Looking in /usr/share/squeezeboxserver/Bin/arm-linux there's no mpddec file like there is in /usr/share/squeezeboxserver/Bin/i386-linux.
Since /etc/squeezeboxserver/convert.conf refers to mpddec for mpc files, I suppose I need mpddec from somewhere, but does it exist for the Pi?

I did notice that the apt package mpc123 is available, if there's no mpddec can mpc123 be used instead?

I think wmadec is also missing, since while all my Squeezeboxen will happily play wma files natively, I can't play them back on my iOS iPeng players, since they require the files to be transcoded by the RPi server.

Can anyone let me know what I need to do to get the mpc and wma files transcoded on the RPi server?

Thanks
