    thread module on NetBSD

    I've compiled Python 2.3.3 on NetBSD and the thread (and therefore the
    threading) module is not available.
    Am I missing the module because of the way I made the binary?
    I could use the dummy_threading module, but then I'm sure I'd run into
    deadlocks.

    Thanks

      NetBSD has finally gotten around to supporting threads, but
      you'll have to install 2.0 beta for that. NetBSD 1.6 does
      not implement threads, so they won't be supported in Python
      there. I occasionally use an early 2.0 beta, and it works
      pretty well for me, but I don't expect the ports coverage
      is very good yet.

      Speaking of ports, I see there is a python23-pth-2.3.4nb2,
      which might be what you need if GNU pth will serve in place
      of real threads. I assume that's what "pth" refers to, I
      have no experience with it (but have used GNU pth on NetBSD.)

          First of all, what you refer to as "ports" here are known as
          "packages" in the NetBSD world since "ports" was already being used
          to refer to "ports of the OS to different platforms".

          More specifically, yes, the pythonXY-pth packages are built
          against the GNU pth library to provide thread support and should
          suffice for NetBSD 1.6.x. As Donn suggested, if you upgrade to a
          later version (1.6X or 2.0*) you can just use the python package
          with native pthread support. If you can't find it prebuilt, look
          into using pkgsrc, which should be fairly painless (and quite
          convenient.)
