Some fortran compiler is needed despite a config option to turn off
Fortran support, because that config option doesn't work properly. A
repearted "make", "make", "make" usually finished the compile. but
that isn't very clean. I can look into that, but since Sage needs a
fortran compiler we can just add sage_fortran to the list of compilers
to look for.

Hhm, it dumped core because "Cannot detect CPU throttling"? This is a
new bug, unless the same think happens for you in case you use 3.7.37.
Could you try 3.7.37 and in case it fails send me the whole log file?

Well, "it works for me" has never been enough to turn an optional into
a standard package. A first step might be to have some special flag to
compile ATLAS instead of gsl's cblas or F77 BLAS for now so we get
some more testing out there for people who want to try and default to
the old mode until all the known kinks are worked out. I will compare
performance of gsl's blas vs. ATLAS for LinBox and if it really is a
factor of 10 I will try to get all the issues worked out before SD6.
