How do I tell ffmpeg's configure and/or make to use the 1.2rc1 version

At present, here is where I am stuck:

I got the speex-1.2rc1 tarball from <a class="moz-txt-link-freetext" href="http://speex.org/downloads/">http://speex.org/downloads/</a> and
./configure, make, and sudo make install worked fine, placing a
different (and slightly larger) version of the headers in
/usr/local/include/speex/:
~/src/ffmpeg$ grep speex_header_free /usr/local/include/speex/*
/usr/local/include/speex/speex_header.h:void speex_header_free(void *ptr);
Now again, how do I tell ffmpeg's configure and/or make to use the
1.2rc1 version of libspeex in /usr/local/include instead of the older
debian/ubuntu libspeex-dev package in /usr/include/speex?
Background: It turned out that in order to build ffmpeg with
./configure --enable-libspeex, I apparently needed the debian/ubuntu
package called libspeex-dev. There doesn't seem to be any
documentation hinting at this, and configuring without that package
fails without a really useful or explicit error message to help solve
the problem; please see the transcript excerpts below.
This thread was particularly useful:

If you think configure made a mistake, make sure you are using the latest
version from SVN. If the latest version fails, report the problem to the

Include the log file "config.err" produced by configure as this will help
solving the problem.

<pre wrap="">I'm quite sure you won't find an answer to the first question here, you'll
have to ask in some Adobe-Flash centric forums.
As for the second question, once you have a file with speex audio, you can
use speexdec (included in speex distribution) to convert it to a PCM Wave
file (*.wav), or a raw PCM file.
