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?
