    # You should be careful when attempting to replicate following in your
    # setup, because setting LD_LIBRARY_PATH is often a bad idea.  Nevertheless,
    # it is okay here in Travis, and actually any attempt to change these led me
    # to linking failures.  Side note: I am not a Linux expert, and you may be
    # more lucky.

    # I'd be happy to get rid of LD_LIBRARY_PATH eventually in some future
    # pull request.
