Thanks for the help.

As I'm stuck in Tokyo due to plane problems, I tried to take some time
to look into fixing it.  Building the preload module from the svn tree
seems to work fine, but from the spec file, it dies with the following
errors:
        /tmp/stapr2YkJ8/preloadtrace.c: In function 'function_gettimeofday_ns':
        /tmp/stapr2YkJ8/preloadtrace.c:2291:3: error: implicit declaration of 
function '_stp_gettimeofday_ns'
        /tmp/stapr2YkJ8/preloadtrace.c: In function 'systemtap_module_init':
        /tmp/stapr2YkJ8/preloadtrace.c:5448:3: error: implicit declaration of 
function '_stp_init_time'
        /tmp/stapr2YkJ8/preloadtrace.c:5703:4: error: implicit declaration of 
function '_stp_kill_time'
        make[3]: *** [/tmp/stapr2YkJ8/preloadtrace.o] Error 1

Which kind of implies that it's a system tap issue somewhere.  Do we
need to update the system tap version in Kernel:HEAD somehow?

Anyone have any ideas?

thanks,
