    # The binary links against these:
    - libreadline
    # libjack must be used from the host system...
    #- libjack-jackd2
    #- libluajit-5.1
    # Required only at runtime.
    # Development packages are not strictly required, but they provide the plain *.so symlinks
    # that LuaJIT FFI expects:
    - libsndfile1-dev
    - libasound2-dev
    - feedgnuplot
    # FIXME: No matter what, we cannot get rid of gnuplot-qt, pulled in by feedgnuplot...
    #- gnuplot-x11
    # FIXME: Why is this required in the image?
