I found that for randomjungle the native inputs must now also include

    ("gfortran" ,gfortran "lib")

in *addition* to the usual

    ("gfortran" ,gfortran)

I can prepare a patch for the three broken packages, but I wonder why
this is necessary.  “gfortran” alone does not install “libgfortran.so”,
only the “lib” output does.
