Hi all:
My PR #3 to solve this problem has been merged. Try the latest commits.

in windows cmd:

>ridk exec pacman -S mingw-w64-x86_64-fftw
>git clone https://github.com/ruby-numo/numo-fftw.git
>cd numo-fftw
>gem build numo-fftw.gemspec
>gem install numo-fftw-0.1.1.gem

This has installed successfully, but now Lurn still does not work.
