Subject: 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.

According to the first part of your message, you wanted a replacement for the IMSL functions, so it's not so much a question of optimization flags, until you choose an open source fft.  You might also consider the Intel MKL library, which should work fine with gfortran.
