Fatal error:gst/gst.h: No such file or directory

Hello.

Trying to somple some examples i got this error in each:

  
Fatal error:gst/gst.h: No such file or directory  

In advanced3dExample, i outrun this kind of error, making symbolic links to any folder or file it ask, that shows that i have the necesary packages.

so, how can i avoid this?, editing the Makefile?

Thanks.
