I was doing exactly that.  The problem was that I needed a fresh checkout.  
Having previously done the ./configure in the source directory caused reconf 
to fail.

I'll try that.

So compilation started for me, but fails....

Making all in pam

It seems to not find fftw, which is installed:


The reason is that fftw.h no longer exists.  FFTW now uses sfftw or dfftw to

I would change to include the right one, but its not clear which one is
