Re: missing library: libgfortran.so.3 on NetBSD

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

With

PKGSRC_FORTRAN=gfortran
GFORTRAN_VERSION=8

in my mk.conf under -current from today it builds fine for me.
However, I do not understand why I get:

 ldd /usr/pkg/lib/libcblas.so.3.9.0
/usr/pkg/lib/libcblas.so.3.9.0:
        -lblas.3 => /usr/pkg/lib/libblas.so.3
        -lgfortran.5 => /usr/pkg/gcc8/lib/./libgfortran.so.5
        -lquadmath.0 => /usr/pkg/gcc8/lib/./libquadmath.so.0
        -lm.0 => /usr/lib/libm.so.0
        -lc.12 => /usr/lib/libc.so.12
        -lz.1 => /usr/lib/libz.so.1
        -lgcc_s.1 => /usr/lib/libgcc_s.so.1
        -lgfortran.5 => not found
        -lquadmath.0 => not found

Why are there double entries of libgfortran and libquadmath?
