Fedora 29 : libgfortran.so.4 not found

[captcha1]

I installed gempak-7.4.3-1.fc26.x86_64.rpm on Fedora 29, but when I try to run anything in /home/gempak/GEMPAK7/os/linux64/bin , I get :

error while loading shared libraries: libgfortran.so.4: cannot open shared object file: No such file or directory

The package libgfortran-8.2.1-5.fc29.x86_64 supplies libgfortran.so.5

The package compat-libgfortran-41-4.1.2-54.fc29.x86_64 supplies libgfortran.so.1

... I don't see libgfortran.so.4 anywhere

The quick and easy solution is to ln -s libgfortran.so.5 libgfortran.so.4 and go from there. But I need to look into this in the fc rpm build.

After I do :

ln -s libgfortran.so.5 libgfortran.so.4

... I get :

./gdlist: /lib64/libgfortran.so.4: version `GFORTRAN_7' not found (required by ./gdlist)
