ffmpeg-php..

Hello,

I know that this question has been answered many times on this forum, and I have read throught all them.

I have read the: http://wiki.dreamhost.com/Php-ffmpeg

Also: http://www.netbrix.net/archives/20

Everything works fine, but I am STUCK in only 1 THING. FFMPEG-PHP.

When I try to use the command: ./configure
it doesnt work for the ffmpeg-php-0.5.0

The folder ffmpeg-php-0.5.0 is being already created. I am on the step to ./configure, it appears that error:
-bash: ./configure: No such file or directory

I have checked on the site NetBrix, and it seems that I have to pass on to the autoconf. Yes, I did it. I have a file called autoconf in my folder /bin.

But why am I still cannot use the command ./configure

Please help me out there!! MY FINAL STEP!!
