>Description:
    In case you compiled a package of the port emulators/qemu with the option
    WITH_KQEMU=yes the installation of this package fails because the absolute
    path of the kernel module is specified in the package list. The following
    error message occurs:

        tar: /boot/kernel/kqemu.ko: Cannot stat: No such file or directory
        tar: Error opening archive: Empty input file: Inappropriate file type or format
        pkg_add: extract_plist: can not invoke 73 byte tar pipeline: /usr/bin/tar cf - /boot/kernel/kqemu.ko|/usr/bin/tar --unlink -xpf - -C /

    It is necessary to strip the leading slash from /boot/kernel/kqemu.ko.
        
>How-To-Repeat:
    # mkdir /usr/ports/packages

    # cd /usr/ports/emulators/qemu

    # make -DWITH_KQEMU package clean

    # pkg_delete 'qemu*'

    # pkg_add /usr/ports/packages/Latest/qemu.tbz
