Pass 4: compilation failed.  Try again with another '--vp 0001' option.
Please try systemtap 1.7, or build one out of
<git://sourceware.org/git/systemtap.git>.  Newer kernels sometimes
break systemtap assumptions; these are fixed pretty quickly in the
source tree, and get rolled into later releases.

Please report any further problems at [off-list ref],
including /usr/bin/stap-report output, if able.
  ok, that solved that problem, but i'm still getting:

/home/rpjday/systemtap/share/systemtap/runtime/stat.c:214:2: error:
?cpu_possible_map? undeclared (first use in this function)

if this is a simple fix, could you enlighten me?  or if it isn't, i
can move this to the systemtap mailing list.
