I just tried to compile ffmpeg (just pulled off the git repository 
yesterday). The drawtext filter is not enabled by default in the 
configure script. However, even when I tried to enable it with 
"--enable-filter=drawtext" - it wouldn't show up in the list of enabled 
filters. After more googling, I found out that it depends on libfreetype 
- so I had to explicitly do "--enable-libfreetype" - then it worked.

It would be really helpful if the configure file would issue a suitable 
warning if one tries to enable the drawtext filter without enabling the 
libfreetype - otherwise many people might go around in circles wondering 
why the drawtext filter is not being enabled.
