While a great many things in Fortran are compiler-dependent, practically speaking well over 90% of the usage in the Julia ecosystem is going to be with gfortran. The only reason anything in base Julia might work at all with ifort on OSX or Linux is due to ifort having gone out of their way to try to be at least mostly gfortran compatible by default on those platforms.
