2-d IMSL fft -> gfortran

Hello,

I have obtained a relatively old fortran code that uses 2-d IMSL FFT routines, forward and inverse.

Is there a gfortran implementation available that I can substitute?

I'm not a fortran programmer, so ...

As far as I can tell, the rest of the code is standard fortran, so any optimization flags to get this code running as fast as possible would be helpful.

I'm running on a Mac OSX Tiger Intel 64-bit machine.

Thanks much.
