John,

I'd give a big thumbs up for including GNU Readline, because it's a constant 
pain to have it installed separately on OSX. The libreadline included in OSX is 
but a halfway functional wrapper around libedit from BSD. Thus, if you don't 
use MacPorts or the like, you're best off keeping libreadline in a separate 
path like /usr/local/alternate to prevent it from interfering with the system 
libraries, and you have to set flags you'd otherwise never touch.

As for FFTW, I'm not sure whether it's a good idea, because depending on the 
CPU, there are many options you can tweak for optimal performance. Can this be 
done automatically?
