[Pw_forum] compilation of pwscf with lahey compiler

don't use fftw-3.0 ! the code is written for fftw-2 . They are 
NOT compatible. This explains many missing symbols.
Other are missing because the f90-to-C linking for Lahey
is not implemented (it's a recent change).
Remaining missing symbols are in the lapack library (likely
compiled with gcc). Try to load -lg2c or -lm
