libmp3lame is not found by configure

[bugzzzz@…]

When I run ./configure on mplayer-export-2010-12-22, libmp3lame is not found by the script. configure displays :
Checking for libmp3lame ... no (in FFmpeg: no)

An error appears in configure.log during the check :

============ Checking for libmp3lame ============

#include <lame/lame.h>
int main(void) { lame_set_VBR_quality(NULL, 0); return 0; }

Result is: no (in FFmpeg: no)

This problem did not happen with older versions like mplayer-checkout-2010-08-09 where mp3lame was located in libavcodec

You need a new enough version of LAME with that function.
