wow, this was missing !

of course it doesn't: most compilers add one underscore to symbols.
Since your blas/lapack symbols have already one underscore, why do 
you want to add one more?

> cft_fftw.o(.text+0xaa1): undefined reference to `fftw_f77_'

is the nag compiler case-sensitive ? if it is, you need to
preprocess these two as well

> dtrtri.o(.text+0x30a): undefined reference to `dtrmm_'

this is either a problem of your libraries or of your way of linking, 
not of the code
