The system you used to built foss-2016b on, probably had gcc FORTRAN installed. The local package was found by pkg_config or LD_LIBRARY_PATH and that is how your foss-2016b is now configured. Its super important to build Easyconfig on systems that are as stripped down as possible otherwise system libraries will pollute your modules.
