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....

It seems to not find fftw, which is installed:

fftw-2.1.3-8
fftw-devel-2.1.3-8


The reason is that fftw.h no longer exists.  FFTW now uses sfftw or dfftw to 
be more explicit about type:

/usr/include/dfftw.h
/usr/include/dfftw_threads.h
/usr/include/drfftw.h
/usr/include/drfftw_threads.h
/usr/include/sfftw.h
/usr/include/sfftw_threads.h
/usr/include/srfftw.h
/usr/include/srfftw_threads.h

I would change to include the right one, but its not clear which one is 
correct in this situation.

Thanks for your help
Matt
