I've finally taken the time to look at the build log files :
http://ftp.es6.freshrpms.net/pub/freshrpms/fedora/linux/7/mplayer/

There, you can see that for x86_64 you have :
Checking for libmp3lame (for mencoder) ... yes

But for i386 you have :
Checking for libmp3lame (for mencoder) ... no

I'm not sure why. Possibly a mach/selinux problem related to i386
builds on x86_64, or simply some bug in my lame packages or the mplayer
configure script.

I'll fix the problem ASAP and I'll keep you posted.
