title: ERROR: libvpx decoder version must be >=0.9.1
body: <p>Heyo! 
  I'm trying to install ffmpeg on my server using the following tutorial:
  <a href="https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuideLucid" rel="nofollow">https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuideLucid</a>
  When I reach the ffmpeg part and run the ./configure command it gives the following error:</p>
  
  <pre><code>ERROR: libvpx decoder version must be &gt;=0.9.1
  </code></pre>
  
  <p>I must mention that my server has Ubunto 10.10 64bit
  I'm a total newbie in linux so please take it into consideration :)
  Thanks a lot!</p>
  
  <p>Following LordNeckBeard solution, I got the following error after the checkinstall:</p>
  
  <pre><code>root@348588:~/libvpx# sudo checkinstall --pkgname=libvpx --pkgversion="$(date +%Y%m%d%H%M)-git" --backup=no--default --deldoc=yes

  no--default is an invalid value for --backup
  
  Use --help or -h to get more information
