ifort compilation error- failes to recognize MKL Lapack function dlange()

Hi, 

  My question is perhaps very bugging since I'm a complete novice.. Could you please advice me about properly linking & compiling my F90 code to use MKL Lapack routines & libraries.. I can already use all MKL Lapack routines without problems but when I try to use a function (like real*8 function dlange), the compilation fails & gives an error like this:

       I have attacked my make file here for reference.. 

details: Using Intel MKL 11.1 on Linux on AMD64 architecture. Multithreaded dynamic linking with LP64. I'm using Intel OpenMP libraries..

I have added *.txt extension just to upload here without problems..

Any & all help will be greatly appreciated! Thanks !
