I thought to compile it I would simply have to untar it and then run make
and make install. not so. After it wouldn't  make I found
http://hugin.sourceforge.net/releases/2015.0.0/en.shtml which states,
"

   - An OpenMP capable compiler is strongly recommended. A compiler without
   OpenMP support creates now executable which runs only single threaded.
   - Hugin is now using some C++11 features. If your compiler does not
   support C++11 it provides a fallback to Boost libraries instead.
   - Changes to dependencies
      - lensfun library and all dependencies of this lib are no longer
      needed.
      - sqlite3 is now needed for camera and lens database
      - libfftw3 is optional, but recommended. With libfftw3 the finetune
      feature and align_image_stack show a significant speed up.
      - libvigra >=1.9 is now required (the internal old vigra library has
      been removed from Hugins source code). Check that libvigra is
compiled with
      TIF, JPEG, PNG and *OpenEXR* support (at least the OpenEXR support is by
      default optional and needs to be activated explicitly during compiling of
      libvigra)"

So I "apt-get install openmp*" and then.... Gosh, I don't know what to do!
any ideas how to proceed?
