The "-lf90" gets added in
scipy_distutils/command/build_flib.py: class sun_fortran_compiler
ver_match = r'f77: (?P<version>[^\s*,]*)'
seems to catch almost any compiler as a sun_fortran_compiler, and I think
that this can happen too often wrongly.
Tom, you may want to fix sun_fortran_compiler for your compiler and send a
Otherwise, you have always a choice to use gcc fortran compiler as
./setup.py build_flib --fcompiler=g77 build
Currently, scipy contains no F90/F95 programs at all.
