I was advised by mc4man to post my problem here:
http://ubuntuforums.org/showthread.php?t=1011926
My problem is :
I successfully installed SNL(http://www.gnomefiles.org/app.php?soft_id=2205) and dependencies like libglib2.0 is pre-installed and so I didnt have any problem so far.
Now to test the installation I ran one of the sample programs here is the code

I couldnt successfully compile it as it continously says glib.h:no such file or directory.
I think the code didnt compile because glib.h couldnt be included its in glib-2.0 now thats a big problem because glib.h has all the include files in glib-2.0/glib/ so glib.h has to be modified!!!!
what should I do?
Modify glib.h or is there any other way?
Please help.
What I meant was : The basic of C programing tells me that if I am including something in linux it must be in /usr/include isn't it?
but this glib.h is in /usr/include/glib-2.0/ so I must do something like this:
#include <glib-2.0/glib.h>
Now I figured out that glibconfig.h is in /usr/lib/glib/include/glibconfig.h now how would a C program knows that address? It will unsuccessfully search for /usr/include/glibconfig.h and return an error.
Am I missing something?
Please help me.
