I'd recommend q-tools. It will give you a (statistically collected)
call-graph, in addition to the flat profile and is completely
unintrusive (no recompilation etc needed). See my post for details:
http://marc.theaimsgroup.com/?l=linux-ia64&m\x107075994721581
Oh, yeah, I'm slightly biased... ;-)
The one limitation is that it doesn't work well for short-lived
processes. Also, it works in system-wide mode (collects info for
_all_ processes that happen to run over a given period of time).
If you want per-process profiling, you could use qprof. It doesn't do
call-graphs (yet) and only works for dynamically linked programs, but
it's very easy to use. See:
