[Speex-dev] compiling ffmpeg with --enable-libspeex (was Re: from Adobe Flex / Flash Player 10 .flv Speex via Red5 to .wav PCM?)

I am having trouble compiling ffmpeg to support speex, which didn't
work with the ubuntu libspeex-dev package, but looks like it might
with the Speex version 1.2rc1 tarball from http://speex.org/downloads/

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?

At present, here is where I am stuck:

~/src/ffmpeg$ make
gcc -L"/home/jsalsman/src/ffmpeg"/libavdevice
-L"/home/jsalsman/src/ffmpeg"/libavformat
-L"/home/jsalsman/src/ffmpeg"/libavcodec

collect2: ld returned 1 exit status
make: *** [ffmpeg_g] Error 1

~/src/ffmpeg$ grep speex_header_free /usr/include/speex/*
[no matches]

~/src/ffmpeg$ ls -l /usr/include/speex/

-rw-r--r-- 1 root root 13179 2008-05-07 14:14 speex.h

-rw-r--r-- 1 root root  4355 2008-05-07 14:14 speex_types.h

I got the speex-1.2rc1 tarball from http://speex.org/downloads/ 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:

[Speex-dev] compiling ffmpeg with --enable-libspeex (was Re: from Adobe Flex / Flash Player 10 .flv Speex via Red5 to .wav PCM?)

This is resolved:

apt-get remove libspeex-dev
cd ~/src/speex-1.2rc1/
./configure --prefix=/usr
make; make install
cd ../ffmpeg
./configure --enable-libspeex
make; make install

worked; then I was able to decode a Speex .flv file:

and I am able to play that .wav file as audio correctly.
