https://ask.sagemath.org/question/7817/building-sage-461-from-source-fails-because-of-missing-fortran/?answer=11994#post-id-11994No, this is intended behavior. On OS X (Mac) we provide a fortran (different one depending on the version). The directions about fortran are correct.
On the other hand, it is still less clear than it should be that one needs fortran. There have been a number of changes in the README lately. See [this sage-devel thread](http://groups.google.com/group/sage-devel/browse_thread/thread/5ebd6d34a5122d49#) for (hopefully) some informed responses.
But again, to answer your direct question - no, not a bug.Wed, 19 Jan 2011 13:37:16 +0100https://ask.sagemath.org/question/7817/building-sage-461-from-source-fails-because-of-missing-fortran/?answer=11994#post-id-11994
