There are three libraries that RD uses for 'MPEG support'.  Specifically:

Lame - MPEG Layer 3 (aka 'mp3') exports

TwoLame - MPEG Layer 2 (aka 'mp2') exports, as well as L2 capture on ALSA and 
JACK.  L2 captures on HPI setups use the onboard hardware codec

LibMad - MPEG Layer 2 and 3 imports, as well as L2 playout on ALSA and JACK.  
L2 playouts on HPI setups use the onboard hardware codec

Just because RD has been built with MPEG support doesn't necessarily mean that 
it will work at runtime -- the relevant libraries have to be available.  When 
caed(8) is started, it will list what libraries have been detected in the 
syslog (LogInfo priority).  Generally, that should be the first place to look 
when having problems with getting MPEG to work.

Cheers!
