First of all, why build the dependencies from source if there are packages 
for your 
distribution ? See http://gstreamer.net/releases/redhat/ for more info.
Make sure you install the -devel packages as well.

Second, why build GStreamer from source if there are packages for it as 
well ? ;)

Third, if you do decide to do everything from source, you need to learn 
how configure works and what it does exactly.  For one thing, check 
config.log and search for a52 and mpeg2 and look why it is failing the 
build.  My guess is, it's not picking up your headers because they're not 
in a standard place.

The solution to that is, basically, "convert all those libs to pkgconfig".  
Failing that, you might get away with checking output of ./configure and 
seeing if for those libs you can specify paths, or, setting your CFLAGS 
before running configure.

But if you've never done that sort of thing before, you'll be in a lot of 
pain until you figure this all out, so if you just want to give GStreamer 
a try, go for the packages.
