    Hmm.  Yes, before that cleanup libc was doing TLS calls even for
    non-threaded, non-TLS programs, and if such a binary is run on FreeBSD
    or an older version of DragonFly it would fault-out with a non-existant
    system call.

    The buildworld process is supposed to use natively-built binaries for
    the build itself but there are a number of chicken-and-egg issues, such
    as with the compiler, which requires building an architecture-native
    version of the compiler using DragonFly libraries, and that is 
    probably what was causing your problems.

    But this is only delaying the issue.  After the release we are going to
    start working on libc5 and most other libraries will need their major
    revs bumped too, as well as switching to gcc3 and almost certainly using
    static TLS storage natively in the new libraries.  Once we do that there
    is no going back.
