no... ok, I did it this time.

yes.

Thanks. there, I found the problem. the new ffmpeg is still using the
standard libs:

$ type ffmpeg
ffmpeg is /opt/new/bin/ffmpeg

$ ldd `which ffmpeg`
        libavformat.so.50 => /usr/lib/libavformat.so.50 (0xb7f6a000)
        libavcodec.so.51 => /usr/lib/libavcodec.so.51 (0xb7b31000)
        libavutil.so.49 => /usr/lib/libavutil.so.49 (0xb7b2d000)

        libz.so.1 => /usr/lib/libz.so.1 (0xb7af8000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7af5000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7aa4000)

        libmp3lame.so.0 => /usr/lib/libmp3lame.so.0 (0xb78cd000)
        libfaad.so.0 => /usr/lib/libfaad.so.0 (0xb788d000)
        libvorbis.so.0 => /usr/lib/libvorbis.so.0 (0xb7866000)

        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb748e000)

But I've configured it to use something else:

$ ffmpeg -i
FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard
  configuration:  --prefix=/opt/new --libdir=${prefix}/lib 
--incdir=${prefix}/include/ffmpeg --mandir=${prefix}/share/man --enable-shared 
--enable-pthreads --enable-gpl --disable-bktr --disable-dv1394 
--disable-network --disable-simple_idct --disable-ffserver 

This is how I config:

configure --prefix=/opt/new --libdir='${prefix}/lib' 
--incdir='${prefix}/include/ffmpeg' --mandir='${prefix}/share/man' 
--enable-shared --enable-pthreads --enable-gpl --disable-bktr --disable-dv1394 
--disable-network --disable-simple_idct --disable-ffserver 

How should I fix then? 

thanks a lot!
