I don't immediately see why this is failing, and I don't have an ubuntu
install around. It seems you followed
http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu correctly. And it
is strange that trace-open.stp does work, but socket-trace.stp doesn't.
Are there other examples (http://sourceware.org/systemtap/examples/)
that do/don't work?
Maybe you can try running the testsuite (make installcheck would be
ideal) and/or upgrading to a newer systemtap (either the last release
0.7.3 or current git http://sourceware.org/systemtap/getinvolved.html)
to see if that gives more hints of what is going wrong in this case.
Cheers,
Mark
