Then I was wrong: the next error is related. The fact that pkgload() hid this
message is why I suggest not using it.

When did you install gfortran? Gaurav Khanna has the unfortunate habit of
uploading new builds without changing the filename.

Try installing the cctools package I gave and rebuilding scipy.
