flib is now deprecated, and has been surpassed by libxtract, which is a
generic C library that includes as an example a PD external that wraps
it's functionality. 

It can be found at http://sourceforge.net/projects/libxtract. If you
want to use the fft-based autocorrelation you will need the fftw
library, and to compile libxtract with --enable-fft.

It includes a time domain and fft-based autocorrelation, but no
arbitrary cross correlation functions. 

Chuck, I must remember to add your cross-covariance code into libxtract
(with acknowledgement of course).

best,

Jamie
