Problems rebuilding ffmpeg to include libfaac

Got an iphone for Christmas. I want to be able to stream videos to it from my MythTV setup. Looking through the MythTV wiki, step one is to get ffmpeg to transcode videos to a format that the iphone can use. I tried the ffmpeg that came from rpmfusion for my Fedora 11 installation. It lacks libfaac support.

To try to fix this and preserve all the yum dependencies, I decided I should download and build the source rpm. (Is this the best approach?) I downloaded and installed ffmpeg-0.5-3.fc11.src.rpm, which matched the version from 'rpm -qa | grep ffmpeg' on my system. Looking in the ffmpeg.spec file, I found these lines:

%{?_with_faac:BuildRequires: faac-devel}

    %{?_with_faac:--enable-libfaac --enable-nonfree} \\\

<whine>I also found this comment in the changelog:

- Don't build faac by default because it's nonfree. (kwizart)

I thought the purpose of rpmfusion was to provide the software that Red Hat and Fedora did not want to ship but people wanted on their computers. So why not include the software for something as popular as ipods and iphones?</whine>

I uncommented those two lines and ran 'rpmbuild -ba ffmpeg.spec'. The first time, it failed with a list of devel packages I needed. I installed those with yum. Then it ran for a long time and then errorred out at the end with these statements:

RPM build errors:
File not found by glob: /root/rpmbuild/BUILDROOT/ffmpeg-0.5-3.fc11.i386/usr/lib/lib*.so.* File not found by glob: /root/rpmbuild/BUILDROOT/ffmpeg-0.5-3.fc11.i386/usr/lib/i686/lib*.so.*

This is what does exist in those directories:

# ls /root/rpmbuild/BUILDROOT/ffmpeg-0.5-3.fc11.i386/usr/lib
libavcodec.a  libavdevice.a  libavformat.a  libavutil.a  pkgconfig vhook

# ls /root/rpmbuild/BUILDROOT/ffmpeg-0.5-3.fc11.i386/usr/lib/i686/

So my question is this. What don't I know that is required to run rpmbuild on the ffmpeg src rpm? What do I need to install or do to make this work?
