I think you've found a bug in the makefile.
We have
LINBOX depends on ATLAS
ATLAS depends on LAPACK and PYTHON
LAPACK depends on FORTRAN
It is just a *lucky coincidence* that the Sage build has actually worked.
We need to add BLAS as a dependency of LAPACK, e.g,.
$(INST)/$(LAPACK): $(INST)/$(FORTRAN) $(INST)/$(BLAS)
$(SAGE_SPKG) $(INST)/$(LAPACK) 2>&1
Then everything should work fine, since depence is transitive.
