ffmpeg srpm missing makefile

hi all

i'm trying to build an ffmpeg rpm with amr_nb installed
but this line is causing me grief when i try to run rpmbuild

on line 121 of the ffmpeg.spec file
cp -f makefile.gcc makefile

it exits with this error message
+ cp -f makefile.gcc makefile
cp: cannot stat `makefile.gcc': No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.43361 (%prep)


RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.43361 (%prep)

i followed the instructions on this page,

i'm using the latest ffmpeg srpm downloaded from dag.wieers.com for RH ES3

thanks
