SystemTap on Fedora 11

Hi,
I plan on doing some systemtap development on a Fedora 11 G5 box.  Started out by just installing the F11 systemtap rpm and tried the HelloWorld example from /usr/share/doc/systemtap-0.8/examples/general, but I get a bunch of error messages, as follows:

[ppcteam@localhost general]$ sudo stap -p4 helloworld.stp
parse error: command line argument index 1 out of range [1-0]
        at: operator '' at /usr/share/systemtap/tapset/argv.stp:15:29
     source:       %( $# >= 1 %? argv[1]=@1 %)
                                         ^
parse error: command line argument index 2 out of range [1-0]
        at: operator '' at /usr/share/systemtap/tapset/argv.stp:16:29
     source:       %( $# >= 2 %? argv[2]=@2 %)

..... lots more of the same kind of thing

The verbose option doesn't help any.  I'm just getting my feet wet with SystemTap, so maybe this is something simple I'm missing.  Any idea what might be causing this?

Thanks.
