Error comes from that the ifort compiler is not found, it's not an error 
of QE but your computer system.
Solutions:
- You re-check the ifort compiler if it is available on your computer or 
not? Then "make w90" again.
- Maybe, you can use other compilers such as gfortran or g95 if you 
don't have ifort compiler. Then "make w90".
- If you want run parallel, you need mpif90 compiler.

Good luck,
