Step 1: Install the speex development headers (on Raspbian they're in package
libspeex-dev)

Step 2: Run the configure script again, and build as usual.

By the way, the parameters that you currently give to configure look strange:
what purpose do "--disable-rpath" and
"--with-module-dir=/usr/lib/pulse/modules" serve?

ffmpeg is different from speex, it's not possible to disable ffmpeg.

In what way is the audio distorted? "Totally distorted" should never be the end
result, no matter what resamplers are enabled, unless "totally distorted" means
that the audio is pausing/skipping (which can be a result of buffer underruns,
which can happen if the CPU load is too high).

By the way, can you explain in more detail what you mean by "music streaming
via Bluetooth"? Do you play files on the RP to a Bluetooth headset, or do you
play music from e.g. a mobile phone to speakers connected to the RP? I guess
the latter, since HifiBerry AMP is involved...
