Anna,

  It's not really possible to give an exact diagnosis from the information 
you gave. As you say, something is going wrong at the linking stage 
(lapack and blas).
  The error message you posted is from the lapack library saying it can't 
find any BLAS routines. That can happen with some compilers if you get the 
BLAS and LAPACK libraries in the wrong order on the link line (lapack then 
blas) But I doubt that is the real problem or at least not in all the 
cases?.

  Focus on mkl (and I assume the intel compiler) - I think that might be 
the easier one to solve first. Can you post the following information:

1) Which version of Wannier90
2) which version of ifort (and the platform)

3) The link line and the first few error messages, ie scroll back up to 
find a line like:
   ifort wannier_prog.F90 -O2 -Vaxlib  constants.o io.o utility.o 
parameters.o hamiltonian.o overlap.o kmesh.o disentangle.o wannierise.o 
plot.o transport.o -lmkl_lapack  -lmkl -lguide -lpthread -o ../wannier90.x
make[1]: Leaving directory `/scratch/jry20/WANNIER90/WAN1.1/src'

4) Have you managed to compile any other program using lapack and blas on 
your machine?
