The Sage packages that directly depend on Fortran are: R, f2c,
lapack, blas, numpy, scipy, cvxopt:
deep:sage-4.5.3 wstein$ grep FORTRAN spkg/standard/deps
$(INST)/$(FORTRAN) \
$(INST)/$(R): $(BASE) $(INST)/$(PYTHON) $(INST)/$(ATLAS)
$(INST)/$(ICONV) $(INST)/$(FORTRAN)
$(INST)/$(FORTRAN): $(BASE) $(INST)/$(PYTHON)
$(INSTALL) "$(SAGE_SPKG) $(FORTRAN) 2>&1" "tee -a
$(SAGE_LOGS)/$(FORTRAN).log"
$(INST)/$(F2C): $(BASE) $(INST)/$(FORTRAN)
$(INST)/$(LAPACK): $(BASE) $(INST)/$(FORTRAN)
$(INST)/$(BLAS): $(BASE) $(INST)/$(FORTRAN)
$(INST)/$(NUMPY): $(BASE) $(INST)/$(PYTHON) $(INST)/$(FORTRAN) $(INST)/$(F2C) \
$(INST)/$(SCIPY): $(BASE) $(INST)/$(FORTRAN) $(INST)/$(F2C) \
$(INST)/$(CVXOPT): $(BASE) $(INST)/$(FORTRAN) $(INST)/$(F2C)
Note that numpy can be built and used *without* fortran, e.g., when I
removed fortran from psage I kept numpy...
