this line above should be
FFT_LIBS=-L/usr/local/lib -lfftw
or something similar, since it was not meant to be a library path, but a linking command 
(please see espresso user guide and troubleshooting)

> LAPACK_LIBS=/usr/local/espresso-4.0.5/flib/lapack.a 
> BLAS_LIBS=/usr/local/espresso-4.0.5/flib/blas.a

this instead is fine since it gives a path to an object file (better, an archive of object 
files)
