[ptx] hugin build fails - undefined reference to `fftw2d_create_plan'

[Bruno Postle]

There is a problem building the latest hugin CVS, it now fails when 
it gets to 'autopano':

fftw2d_create_plan is in /usr/include/fftw.h on this system, which 
is provided by a fftw2-double-devel package - This hasn't changed in 
months.
