If you can't upgrade (or upgrading doesn't fix things), you can also do
something like this before the IPC call:

    # HACK HACK HACK
    # Fix for running IPC::Run under FastCGI
    # See: http://www.mail-archive.com/ports@openbsd.org/msg16948.html
    #
    unless (exists &FCGI::Stream::FILENO)
    {
        *FCGI::Stream::FILENO = sub { return -2 };
    }


HTH,
