That would indeed be a problem. Chris might not be reading this thread, so
hopefully my changing the subject line will grab his attention.

No, as the website says:

"""To avoid compatibility issues, you should install the gFortran compiler and
the GCC 4.0 compiler tools (both also included) before installing these packages."""

Install the gfortran compiler given in the tarball. It contains the runtime
libraries that all of the scipy fortran wrappers compiled against.
