Adam, is this julia codebase a fresh clone, or have you been building out of this directory for a while? If it's not 100% fresh, you might want to try running `make -C deps distclean-fftw` and then trying again. It's possible that we fixed this issue a while back, and the cached configure state of your fftw is behind a bit and needs to be reconfigured. -E
