I think you may need to run ldconfig after editing /etc/

Find the libXext.a file on your system, e.g.,

$ find / -name libXext.a

If you don't have it, do you need it?  Try compiling without -lXext.  
If you do have it, try specifying its directory with -L before the -lXext.
If that doesn't work, try specifying the full path name, e.g.,

$ gcc -o hello hello.c -lMesaGLU -lMesaGL /where/ever/it/is/libXext.a -lXmu -lX11 -lm -L/usr/lib
