You are trying to run systemtap as a normal user.
You should either be root, or be part of the group "stapusr" and possibly one
of the groups "stapsys" or "stapdev".

Usage: stap [options] FILE         Run script in file.
   or: stap [options] -            Run script on stdin.
   or: stap [options] -e SCRIPT    Run given script.
   or: stap [options] -l PROBE     List matching probes.
   or: stap [options] -L PROBE     List matching probes and local variables.

Options (in /home/mark/.systemtap/rc and on command line):
   --         end of translator options, script options follow
   -h --help  show help
   -V --version  show version
   -p NUM     stop after pass NUM 1-5, instead of 5
              (parse, elaborate, translate, compile, run)
   -v         add verbosity to all passes
   --vp {N}+  add per-pass verbosity [00000]
   -k         keep temporary directory
   -u         unoptimized translation 
   -w         suppress warnings 
   -W         turn warnings into errors 
   -g         guru mode 
   -P         prologue-searching for function probes 
   -b         bulk (percpu file) mode 
   -s NUM     buffer size in megabytes, instead of 0
   -I DIR     look in DIR for additional .stp script files, in addition to
              /home/mark/install/systemtap/share/systemtap/tapset
   -D NM=VAL  emit macro definition into generated C code
   -B NM=VAL  pass option to kbuild make
   --modinfo NM=VAL
              include a MODULE_INFO(NM,VAL) in the generated C code
   -G VAR=VAL set global variable to value
   -R DIR     look in DIR for runtime, instead of
              /home/mark/install/systemtap/share/systemtap/runtime
   -r DIR     cross-compile to kernel with given build tree; or else
   -r RELEASE cross-compile to kernel /lib/modules/RELEASE/build, instead of
              /lib/modules/2.6.32-220.7.1.el6.i686/build
   -a ARCH    cross-compile to given architecture, instead of i386
   -m MODULE  set probe module name, instead of 
              stap_9722
   -o FILE    send script output to file, instead of stdout. This supports
