on debian testing.

dub is installed via apt-get.

Should I revert to an earlier version?  Or what?

The program:


import    std.stdio;

void    main()
{    //int[]    t1;

    //t1    ~=    1;
    //t1    ~=    2;
    //writeln ("t1 = ", t1);
}

fails with the 442 lines of error:

Are you on Ubuntu 16.10, or some other system with an hardened toolchain? If that's the case, you should compile with `-fPIC -defaultlib=libphobos2.so`. You can put those options in your dmd.conf configuration file, so that you don't have to type them every time.

Well, I'm using debian, but I've never had to do anything of that nature before.  OTOH, it's been a couple of months if this is a new change.
