error compiling basic example

Dear Whizard team,

I just follow the instruction in the recent manual on installation. When I try to compile the hello.sin, everything is fine. However, as I try to do the same with ee.sin, I got the following error

It seems like there is a problem with fortran cimpiler. I have gfortran, gfortran-5, and gfortran-7 installed on my Ubuntu 18.04. Can you help me with this problem?

Best regards.
