I have installed almost everything: ITK, FSL, with many problems due to uncompatibility  of gcc versions etc but I can not install HOPSPACK_main_threaded the precompiled binary file neither from source. it sends the next message:

:/usr/local/bin$ ./HOPSPACK_main_threaded
./HOPSPACK_main_threaded: error while loading shared libraries: libgfortran.so.1: cannot open shared object file: No such file or directory

I have tried different things, the library exists, it is in different paths, one of them: /usr/lib/ another: /home/sarahi/anaconda3/lib/libgfortran.so

If sime one has some suggestions of how to install this software, I have the manual but it is not enought, thank you in advance.

I am working in ubuntu 16.04
